Hare Krishna's always recruiting. You could message one of the members to set you a poll.

Will there be any suitable Group wishing to have me in? How do I know who are the Group leaders?

Basically they are social groups on the forum. If you wish to join one, you will need to message one of the members of the respective group you are wishing to join.

What are the Groups I am seeing over people's Profiles? Are they joinable? None seem to be active. And this place seems dead but I thought I should ask.
