Help:Editing

Basic Editing
To edit a MediaWiki page, click on the edit this page link at the top of the article. 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 useful 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 edit summary in the small text field below the edit-box and when finished press "Save". Depending on your browser, 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 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. However, before you submit your changes, please make sure nobody else has edited the page since you saved your local copy by clicking on the History tab. 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, which will warn you if someone has edited the page since you pressed edit this page .
Minor Edits
When editing a page, a logged-in 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 recent changes page, to keep the volume of edits down to a manageable level.
When to use this is 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".
