Generally speaking, if you click on the "Groups" tab you will see a listing of the various groups. Click on the icon of the group in which you are interested...
Once you arrive on that group's page, you should see a little green cross (+) just below and to the right of the "Invite" tab. It will say, "Join ___________" with the group name where the blank space is. If you click that link you will become a member of that group. Easy huh?
Other groups are by invitation only. Go to that group and fill out the form to request and invitation. If you receive an invitation back, it will show up in your regular email (check your spam can too). You can click the link in your email and that will take you to the group page where you can click the link to join the group.
