Just a suggestion.
I have a few members in my fellowship who are brainknights, thus can only play in 1 tournament of a kind, at a time. This means that if they are in an open backgammon tournament then they cannot enter a fellowship backgammon one. This is a little disappointing for them. It will be even more so when inter fellowship tournaments begin. (and make it harder for fellowships to make up a team)
May I suggest that perhaps instead of limiting them to participating in only one tournament game type at a time that instead they can play whatever game type they like to say a total of 30 games (that number is off the top of my head) This offers much more flexibility especially for those players who only play 1 or 2 game types.
