I'm having the same problem, or a similar one anyway. I'm looking more for just people to sing and play with informally at my University, rather than a performing group. Janitor, I think, thought you meant a gathering of 'folkies', like what I'm trying to do, so for me his advice is good, because some connotations with folk are sort of negative, and some people associated with it are rather cracked (no offence) and among youth the term is looked at skeptically, cause they are thinking.. thats what my parents did. But traditional music, and acoustic music, and blues are still cool and respectable for some reason, even though they are just the definition of folk. His is a good idea that I will use.

So my suggestion to you is to find a local folk club, or a local group that already plays and has a following, or a joint that has a folk open mic sort of thing, and talk to people there.

good luck. have fun.
