I have completed the default templates for cs-ed.org. Now, new blogs will all come in looking and behaving the same. This, I think, is a good thing.
Also, all the blogs should render just fine under older browsers; editing them under old browsers will still be painful, but I’m not about to go hacking on the application itself.
The blog portion of the site is open for business!
Update 21:17:
Pete’s blog went in without a hitch, as far as I can tell; apparently, the default templates worked exactly the way they should.
