free message boards?

Just wondering if anyone has any reccommendations for free message boards... we're trying to set up a portfolio website for my class and we thought a message board would be cool to have. I did a google search and got about a million results, but I have no idea what to go for. Anybody have any good/bad experiences with free message board hosts? Thanks!

Easy to setup
Easy to maintain
And Free

if you are wanting to set something up yourself there many great PHP based forum systems. There is another topic or two where some are discussed.

I got this one free with my Host. I don't know if it costs any money or not. I know a guy that will host them for you dirt cheap if it costs money to buy it. He hosts all of my web sites for me, but one. That PhP board is part of his package. He owns a few servers and has plenty of space on them.
