I have no idea what all those terms mean, but however it happens I would love to be a part of a 1L group blog, I think its a really cool idea.
I mentioned wordpress because I'm familiar with it. But if someone with more expertise thinks moveable type or typepad is better, then I'm perfectly happy to use that instead.I'm only a part time computer nerd. ^_^ I'm hoping someone else will have more expertise. I can however, set up a wordpress page and photoshop a simple banner graphic.
