Added comments, and, links to team home-pages

Folks:

I have added comments for all (well, almost all--Liz outsmarted me!) blog posts to date. Please read and consider those comments.

Also, I have added links to all non-WebCT project sites to the blog homepage (lower-right menu, see "Links"). Please check that list and visit other teams' pages. And, if your project site is not represented in that list, please send me that link ASAP. This of course presumes that the website exists...
