I've been playing around with some of the community's contributions to Blosxom, and it looks like they're going to fill in the "missing bits"
I've added the active category list on the right side, thanks to Michael McCracken, who posted instructions.
I've been trying to get searching and comments, but neither appear to be working correctly. Searching just plain pukes when activated according to instructions, and comments appears to be a one-way street: you can add them, but can't view them...
There's a Yahoo group, where they mention work on a calendar display, too. Cool.
Still, quite promising. I'll keep playing around with Blosxom and see if I can learn some Perl along the way.
