forum software

I'm putting together my first site using coldfusion and would like to add forums, are there any good coldfusion-based forums out there or should I just use phpbb, SMF or some such thing? It's my first time working with forums so any and all comments appreciated!

Also, I'm a bit worried about coldfusion forums seeing as how the search function on this site returns "Variable FTVAR_RESULTTYPE is undefined". 😉
