mctrivia: Yes, we need something, and various ideas have been mentioned over a while

I think the best idea is in a players profile, on the list that says which Teams they are a member of to have a little available yes / no toggle that they can set for each Team. This would then show up beside there name in the appropriate Team (in the pink box).
This would save having to keep leaving & re-joining Teams.
Something that could be added as well, is when signing a Team up for a Team challenge or Tournament, the system could then check each player to make sure they are eligible to play in a certain Tournament / Match

When a Team is entered for ANY competition, i think every player who has been picked should get a *IMPORTANT* PM sent to them to let them know.
i.e. You have been selected to play in XXXXXXXXXXXXXXXXX starting XX/XX/XX please contact either Team Captain or Big Boss if you are unable to play.

I think that would help a lot of Captains / Bosses out, not having to change Teams and find new players.

A thing that i mentioned to Fencer a few weeks ago, is the ability to change a Team play if the Tournament has started BUT the player has not played a move.
Really, being a Team competition, you should like every other game in the world be able to change a player any time as you are working towards a common goal.
This of course brings into the structure of Teams here, should our own rating matter, or should Team ratings be just that, Team BKR Ratings worked out on there results wins, losses and draws

I say yes myself lol
