Where does one find volunteer Perl hackers?
I know your question is "where" but I think first you need to answer the question "how" and think your attraction strategy over. A permanent acount on some website does not sound very exciting. Maybe you could describe it a bit more? Maybe you could present it as an working in an exciting new programming paradigm or something? Or maybe it would be a site full of attractive young females - and the core coder could automatically became their hero?
