To sign up for the wiki, simply click the yellow "Join Now" button near the upper right corner of the homepage. When you've created an account, you'll probably want to edit your mail settings right away, or else you may find yourself innundated with wiki update notifications. Also, you'll probably want to turn off the "Hide Edit Note window when saving changes" feature on the preferences tab. Once you sign up, please add yourself to the end of the member bios page, following the formatting conventions that you see in the other members' bios. Other useful information:

The navigation pane can be expanded by dragging the dotted rectangle at its bottom edge. If a page seems misplaced, you can move it in the hierarchy by navigating to that page and clicking "more tools > move page." First, choose the page you want to be its parent in the heirarchy (all top-level pages are children of "Home"), then choose the order you want it to appear relative to its sister pages.

To add attachments to the wiki, click "more tools" and upload your file. The attachment will be tied to a specific wiki page and will show up in the "attachments" section below the discussion thread tool at the bottom of the page.

If there are a few pages or discussion threads you are particularly interested in you can choose to "watch" only those pages or threads, meaning you will receive emails when someone updates those items, but not when changes are made elsewhere in the wiki. To watch a page, click on "more tools > watch page." To watch a discussion thread, click on the thread subject, then click the "watch thread" link on the thread detail page. Alternatively, when you start or reply to a thread, you can simply check the "watch this thread" box within the thread UI. Alternatively, each time you log in you can check the "updates" tab (in the blue bar below the logo) to see all recent updates site-wide.
