ppffff i found 10-20 posts like this one and everywhere your answer is the same. I found the main one (the one you're talking bout), it's cr8 long time ago (when i guess there were lack of users ) and there is no correct answer from any of the team. You should cr8 new pool and if there isn't better job (like fixing bugs) to work little on this one :P It's great idea i think, some symbolic reward like 5 skill points or smt would be great. I saw some suggestions bout tokens rewards but that sucks. Goals and Assists are made by players, they should get better with that.
