I'm working on installing pLog for my wife who is the director of a small non profit in Denver, CO. I installed it on my personal web page to test it out and it looks great! (http://www.ryanandbritta.com/plog). The ease of the installation blew me away. I'm getting ready to put it on her organizations web site. Everyone who worked on this did a great job. I can't wait to really start learning all the inns and outs.
Anyway, my suggestion is to allow users who can post new topics to also post comments to topics. It looks like right now you can only have annonymous comments. One nice thing about allowing at least the regular posters to do comments is that you couldn't impersonate them.
Also, on a side note is there anywhere where the visitors to the blog can see the bio of a registered user?
