From my experience, don't go with YaBB, the few times I tried it, I got nothing but trouble...once again, for CGI, go with Ikonboard, PHP, go with Invisionboard. Also, Geocities doesn't allow any scripts other than theirs.

So, are there ANY forums that can work on Geocities?

If not, what is a host that will give me a free domain (subdomain, nor /you or /dir/you) that has a short name (so I can get me.cool.com for example)

Hi,
as long as you use a redirect domain it's not important what the address to your webspace is. You shouldn't pay any attention to that and just use a redirect servive.

Well, can someone give a link to a place where I can get my-domain.com/forum forwarded to, say members.lycos.co.uk/me/cgi-bin/index.html

Cause I can't find any that would do that, and the only ones that I could find would redirect members.lycos.co.uk/me/home.html to whatever.cjb.net or whatever.vze.net
