Help:Editing

uses Mediawiki to fuel its fan-powered goodness! You can Google Mediawiki for more info on this wiki software.

Welcome
Firstly let us welcome you to the wiki, just like all those that have, do and will edit the wiki you've decided to give something back to the community by making an addition to the combined knowledge compiled here.

General
To edit a page, click on the "Edit" link at top of the page. This will bring you to a page with a text box containing the "wikitext" (the editable source code from which the server produces the webpage). For the special codes, see below.

After adding to or changing the wikitext it is best practice to press "Preview", which produces the corresponding webpage in your browser but does not make it publicly available yet (not until you press "Save"). Errors in formatting, links, tables, etc., are often much easier to discover from the rendered page than from the raw wikitext.

If you are not satisfied you can make more changes and preview the page as many times as necessary. Then write a short in the small text field below the edit-box and when finished press "Save". Depending on your system, pressing the "Enter" key while the edit box is not active (i.e., there is no typing cursor in it) may have the same effect as pressing "Save".

You may find it more convenient to copy and paste the text first into your favorite text editing program (e.g. notepad++), edit and spell check it there, and then paste it back into your web browser to preview. This way, you can also keep a local backup copy of the pages you have edited. It also allows you to make changes offline, but before you submit your changes, please make sure nobody else has edited the page since you saved your local copy (by checking the page history), otherwise you may accidentally revert someone else's edits. If someone has edited it since you copied the page, you'll have to merge their edits into your new version. These issues are handled automatically by the Mediawiki software if you edit the page online, retrieving and submitting the wikicode in the same text box.

Dummy edit
If the wikitext is not changed no edit will be recorded and the edit summary is discarded.

A dummy edit is a change in wikitext that has no effect on the rendered page, such as changing the number of s at some position from 0 to 1 or from 2 to 3 or conversely (changing from 1 to 2 makes a difference, see below). This allows an edit summary, and is useful for correcting a previous edit summary, or an accidental marking of a previous edit as "minor" (see below). Also it is sometimes needed to refresh the cache of some item in the database, see e.g..

Minor edits
When editing a page, a user has the option of flagging the edit as a "minor edit". This feature is important, because users can choose to hide minor edits in their view of the, to keep the volume of edits down to a manageable level.

When to use this is somewhat a matter of personal preference. The rule of thumb is that an edit of a page that consists of spelling corrections, formatting, and minor rearranging of text should be flagged as a "minor edit". A major edit is basically something that makes the entry worth revisiting for somebody who wants to watch the article rather closely. So any "real" change, even if it is a single word, should be flagged as a "major edit".

The reason for not allowing a user who is not logged in to mark an edit as minor is that vandalism could then be marked as a minor edit, in which case it would stay unnoticed longer. This limitation is another reason to log in.

The wiki markup
In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.

You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the Sandbox.

Sections, paragraphs, lists and lines
Summarizing the effect of a single newline: no effect in general, but it ends a list item or indented part; thus changing some text into a list item, or indenting it, is more cumbersome if it contains newlines, they have to be removed; see also ].

Use &lt;nowiki&gt; to suppress interpretation of wiki markup, but interpret character references and remove newlines and multiple spaces:

arrow     &rarr;

italics link  arrow     &amp;rarr;

italics link

Use &lt;pre&gt; to suppress interpretation of wiki markup and keep newlines and multiple spaces, and get keyboard font, but interpret character references:

arrow     &rarr;

italics link  &lt;pre&gt;arrow     &amp;rarr;

italics link&lt;/pre&gt;

Use leading space on each line to keep newlines and multiple spaces, and get keyboard font: arrow     &rarr;

italics  arrow     &amp;rarr; italics link

Use keyboard font:

arrow     &rarr;

italics

 arrow     &amp;rarr;

italics link

Show character references:

Commenting page source: not shown in page
 * Used to leave comments in a page for future editors.

HTML Tables
tables can be quite useful as well. For details on how to use them and discussion about when they are appropriate, see.

Templates
Some part of a page may correspond in the edit box to just a reference to another page, in the form, referring to the page "Template:name" (or if the name starts with a namespace prefix, it refers to the page with that name; if it starts with a colon it refers to the page in the main namespace with that name without the colon). This is called a. For changing that part of the page, edit that other page. Sometimes a separate edit link is provided for this purpose. A convenient way to put such a link in a template is with a template like. Note that the change also affects other pages which use the same template.

As part of the wiki's update to 1.19, we have a section of buttons on the bottom of every page that should streamline and make template usage SOOO much easier... For some details about this, please see the help page for these buttons.

Page protection
In a few cases the link labelled "" is replaced by the text "" (or equivalents in the language of the project). In that case the page cannot be edited.

Position-independent wikitext
Wikitext for which the result does not depend on the position in the wikitext page:


 * (see also above) - the mutual order is preserved, but otherwise the positions within the page are immaterial
 * category specification - ditto
 * ,, see

Separating edits
When moving or copying a piece of text within a page or from another page, and also making other edits, it is useful to separate these edits. This way the can be usefully applied for checking these other edits.
