I'm new to groups, help?

How would I go about "contributing to my team"?

And what group functions do we do, if any?

I believe the primary "activity" of a group is vote chess and team matches. Some groups don't do much of anything. My groups are mostly "Openings" groups where each group is devoted to playing a specific opening in vote chess and team matches. Posting information in the group forum can also be interesting.
