Fencer: You asked, Monkeys on form today

My definition would be:

Big Boss: Every Fellowship option should be possible, though this is not yet possible in one. Even as a BB i can not enter Teams in Tournaments unless i am Captain of it. It is a pain, for whatever reason, having to keep swapping Captains, just to make a Team change.

Little Boss: Every Fellowship option APART from the ones already stated, replacing the BB or deleting the Fellowship.

Now as for Manager / Captain as in essence you can not be one without being the other, they should become one, so just use one.
I think Manager should be used, as Teams in life have player-managers (i often manage Teams here that i do not play in). So get rid of Captains, and replace them with managers.
Well, which ever is chosen they should have all power relating to Teams, Team Tournaments & Challenge Matches, Removing players from Teams, picking Teams and setting challenge matches.

(Of course ALL these option should Automatically be available for Big / Little Bosses)

And while i am here , a couple of things that urgently need looking into.

1. The ability to have substitutes. If a Team player has not yet made a move in a Team Tournament game or Challenge match, they can be replaced. Another one started this week, just for me to find out a player is no longer going to stay at BrainKing, so the Team has lost all those games, and renders the Tournament a loss already.
This has happened many times now and is getting disheartening for Bosses, Captains & the Players left in the match.

2. The ability to put challenge Matches in a Team Challenge waiting room, so Bosses & Captains from all Fellowships can look through and except or get Teams for them.

3. That Team BKR's should be based on Team results, not players overall BKR added and meaned. Players BKR's can be shown in Teams and used for ranking purposes for the draw. At the top of the Team in the Fellowship the Team BKR should be shown.

They are mine (and a few other i know of) Main issues that need addressing
