Allow users to join groups on their own,

on my website gameml.iowoi.org i have about 6 user groups, about the members. i put users in groups, but want them to join on their own. is that possible?

i think the admin of the site has to accept it.. idk lol

thanks....?.?

I don't think so.
At least not expressly.

You can make the group open, so that the user's apply to be in it on their own, but you still have to go through the step of accepting them, placing them officially in the forum.

This is not possible, the group moderator must accept them.
