Potential Club Conflicts?

.Potential Conflicts?

I recently joined several clubs by invitation, not knowing what is or isn't club protocol. Now I've noticed two of these clubs I've joined are playing against each other.  The issue is, I have no clue what I can or cannot do, I want to join in but don't really understand what is expected.  Anyone else going through this?  Are there rules somewhere?  Any pointers would be greatly appreciated.
