SharePoint as a training tool

We are in the midst of adopting SharePoint as a part of our online file sharing and collaboration system. I am in the middle of testing it by putting our Office 2007 training program together. For those of you who don't know anything about SharePoint, it allows us to put out files up on a web accessible system, set permissions on them, create a blog and probably a lot of other things, I haven't gotten to yet. So far I have created a page, written a blog entry, added a link, added RSS links. It truly has been an exciting day!
