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. I'm not 100% sure if it works but if it does, it will be a good way to avoid having to cc a mailing list whenever you update the wiki...
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.)
