So far I’ve found two other message boards: one on the Snopes urban legend website, http://www.snopes.com and the other, for Who Wants to Be a Millionaire, on ABC-TV’s website http://www.abc.go.com but if there are any other message boards, I havent’found out about them.
Any Dopers know of others? Thanks very much. 
You can go to your favorite band’s message board at http://www.imusic.com.

You may find some of the posters familiar

Have you been living under rock?
Oh and if you are into food:
It is more about restaurant recipes but you can find some other ones that are good.
I have more but most of them are pretty specific in nature so it depends upon your interests.
Oh and Cassandra has her board as well but I don’t know the URL.
Sorry, that should be Cessandra, I haven’t seen her much on the boards so my fingers went for the A instead of the E.

Keenspot Message Board (webcomix)
Here’s one that I use a lot, the Internet Movie Database MB. This specific forum is where you post questions like “What movie or TV show had this scene in it?”
PublicSectorZone - for state and local government issues, geared toward those working in government, but also welcomes public comment. In fledgling stage.
If you’re a computer geek, I highly (very highly) reccomend http://www.dualboot.net
Planet Sucks
ZGeek
Imladris’ L.O.T.R. Movie Site
The Force.net
Just a sample of other sites that use the same fine Message Board software as The Straight Dope (and you thought they were the only ones…for shame!)
I have a message board. Not that anyone posts there of course, but hopefully they will once it’s reason for being becomes more valid.
And a good one I post at:
Hmm, seems I buggered up the ACOL url. Try this one:
There are quite a few friendly chaps at http://www.leftbehind.com
really, they love a good chat…

Ever wanted to know how to beat casino’s at blackjack?
Thanx
It’s not a “message board” like this one, but you can post messages in reply to news items and carry on discussions about related things:
Th most popular for tech info is a site I’ve seen referenced here before http://www.zdnet.com/community/
Dozens of specific forums, for the best computer/web advice
A lot of regulars just chat as well, but it runs to shop talk and technonews.
