Not sure on terminology, but for arguments sake I will call the people doing the playing as the "sweatees", and the people watching and offering advice as the "sweaters".
I have a proposal for this concept, one that can be used monthly going forward. I think that whenever the sweatees are in profit from one of these sessions (which should be almost all of the time given that the sweaters will likely be dominate at this level and the advice should be paying off), then any profits from the sessions get amalgamated in a single account, and that money is then used on a monthly freeroll for anyone who acted as a sweater in that month. Sweatees should feel an obligation to donate those profits back to the pool, but also will obviously have the right or ability to donate more to show their appreciation (and obviously if they choose not to donate their profits, that is their choice as well, however, seeing as someone has donated their time to improve your game, I think it is the very least you can do to give back).
I am not sure how much would accumulate in the month, but I would imagine that if there are a lot of Sweatee/Sweater sessions in a month this could really add up.
I am happy to assist with the administration and setting up of this system, but I believe everyone would feel much more comfortable with one of the more senior members/administrators of Cardschat looking after it. I know I would not want to send my money to a junior member for this type of a system. What do you think of that proposal?
