Help:Editing

General
To edit a page, click on "edit" link at the top of the page or along one of its edges.

After adding to or changing the wikitext, press "Show preview", which produces the corresponding webpage in your browser but does not make it publicly available yet (not until you press "Save page"). 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 edit summary in the small text field below the edit-box and when finished press "Save page". 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 page".

You may find it more convenient to copy and paste the text first into your favorite text editor, 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 (you can find their specific edits by using the "diff" feature of the page history). 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. 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.

Minor edits
When editing a page, a logged in user has the option of flagging the edit as a "minor edit". When to use this is somewhat a matter of personal preference. The rule of thumb is that an edit of a page that is 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 relooking at for somebody who wants to watch the article rather closely, so any "real" change, even if it is a single word. This feature is important, because users can choose to hide minor edits in their view of the recent changes to keep the volume of edits down to a manageable level.

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 Playground.

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.

HTML Tables
HTML tables can be quite useful as well. For details on how to use them and discussion about when they are appropriate, see MediaWiki User's Guide: Using tables.

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 template. 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 m:Template:ed. Note that the change also affects other pages which use the same template.

Page protection
In a few cases the link labeled "" is replaced by the text "". In that case the page can not be edited.

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 diff function can be usefully applied for checking these other edits.

Trolls
The bad news is that occasionally a Wiki Troll or vandal will deface a page. The good news is that any page can be reverted back to a previous version:

''Simply click "history" at the top of the page you wish to roll back. Then click on the time and date of the archived version you want to revert back to. The page will appear with the version indicated at the top of the page, just underneath the page title. Next, click "edit" at the top of the page. Add a note in the Summary box that you are reverting the page because of a vandal, and then click "Save page".''
