Notice that the avatars for posts in non-league threads will consist of the various teams and leagues a GM is in. As many GMs are in multiple leagues with multiple teams, posts in common areas outside of their league will show all the teams a GM runs. We can get fancier with that but you get the idea.
When posting in your own league forum (you must be granted access and part of that group), the avatar of your assigned team will show as usual. If you switch to a different league, your avatar will change depending upon what league you are posting.
Thanks
