Navigation
Getting around this site should be pretty painless. Most links you see are links to other pages on the site. If you see a question mark after a page name that means the page doesn't exist yet.
Links to other sites will either be written out, e.g. 
http://www.viatasso.com/, or
will have a small icon (
) to let you know the link is to an external site rather than some
other page on this site. E-mail links are indicates the same way, just with a
different icon (
).
Editing
The feature that sets this site apart from most other web sites is that anybody can edit any page just by selecting the "edit this page" link found at the bottom of every page. Sites like this are called wikis.
When you select the editing link you'll see the text of the page in a large text box. One of the wiki goals is to make things as simple as possible, so you won't find HTML markup in this box. Instead, pages are written in a unique format made to resemble as much as possible how you would write an e-mail message or other plain text document.
For example, text that is /surrounded with slashes/ is
italicized. If you begin a line with an asterisk (*) it
becomes a bullet. You can create links to other pages by putting
[brackets] around the page title.
You'll find a complete list of all of these rules at the bottom of the edit page. If you want to try this stuff out I recommend you play around in the sandbox.
