I would never ever trade one of my players to sb. else in my league unless I wanted to cheat.
I'm not really getting this statement. If you want to cheat how would you achieve that by trading with other teams in the Österreich Bundesliga?
and if you want you can sell a player to team X and then buy your desired player from team x anyway.
Not really, often some other random BB user intercedes and the "trade" process doesn't go smoothly. I think that a trade system that I suggested could coexist with the transfer system and help out BB.
