I just had a great experience installing and configuring free message board software from Snitz
. It was no hassle and I had something up a couple of minutes after I downloaded it. I didn't bother to read the instructions, it told me what to do when I pointed my browser to it.
If I could have one thing, I'd like a totally anonymous board. With Snitz, users need to register before they can post--I like the NNTP (give any name you want when you post) style. It's the kind of style you see at JoelOnSoftware
or F'd Company
