They are still on AOL, but not too many people post there now. Eveyone from the Straight Dope moved from an AOL area to a website on the web, so they can be accessed from anyone. There is a messageboard on their website, you just have to sign up for a name and password for yourself, it takes a few minutes and is free. I haven't posted there in a long time, if you start posting there maybe I will pick it up again. I have been wanting to go back there for a while, but haven't forced myself far enough yet. I think part of it may be that I made too much a fool out of myself back when they were still booming on AOL. Anyway, the link to the main Straight Dope website is below, it's very easy to remember.
