No problem dude - if you feel you can trust me, send me your account details, mySQL details and the name of the folder you'd like it in, and I'll install it for you (you can change your passwords when I'm done)
If not, let me know which day you'd like to give it a shot and I'll try to be around for troubleshooting/assistance
You can use either phpBB or Invision Power Board on Smoove - or any other php based forum (they don't allow CGI) - depends a bit on what you want to do with it. IPB has more features as standard, but is harder to modify (not in terms of appearance, but in terms of features). phpBB is pretty easy to modify and there are plenty of modifications out there. Personally I think most of them aren't worth the time - the only handy ones are ones that make forum management easier, and then you might as well have gone with IPB imho
IPB also uses less bandwidth and runs faster, which is nice.
Let me know, either here, by email or by PM and we'll arrange something
