Tripod is still around. I still have an account there from 2001, but unfortunately nothing is hosted there now but a default landing page.
It still has a cgi-bin, but I have no idea if perl scripts will run in it.
And surprisingly enough, Angelfire still exists. I just learned they're both sharing a database being run by Lycos because I tried to recover an old Angelfire account and it complained that my new password was the same as my Tripod account.
I can't remember if I actually got a forum from Matt's Script Archive running on Tripod, but I do remember writing by own horrible text-based forum that no one else used.
