master656, try to use everything on the site, especially things mentioned in the newsletter, and give us feedback of what you like, what you don't like, what you think should change, any bugs you encounter. Pay attention to the newsletter tidbit that says that links which don't do anything are probably not implemented yet. But if you click a link that's supposed to do something, and it doesn't do what you expect, let us know.
When you do, let us know which operating system you're on (Windows, Mac, Linux), which version (Windows 7, Xp, Mac OS X, Ubuntu Linux 10.10, etc), which browser you're using, and the version of the browser.
