Forgive the ignorance, am new to the site.... how do I locate/join/interact with ''clubs" of other members?

Haven't mastered the art of navigating the page yet and can't seem to locate.

many thanks.

go to usercp at the top of the page.
then on the left, click on group memberships
then on the right side of the screen, click on join group!!

You can also create 1 of your own (If there is not one you like from the
list of options) however it will not be in Red. While still in "user cp" then
select "edit profile" and then choose "custom user title" type in what it
is you want and save the changes. It will appear under your User Id :D
