Watching a Page for updates
Note that when you edit a page on the wiki, there is a checkbox you can click to be notified of updates to the page. It is a good way to avoid having to cc a mailing list whenever you update the wiki...
To make it works you need enabled e-mail notification in your Wiki account. To do it click the "My Preferences" link at the top of the wiki web page and select appropriate checkboxes.
Editing a whole page
Note that if you want to edit the WHOLE wiki page instead of just the section, click the Edit button in the left Navigation bar (Just below Views, Article, Discussion.)
