I believe realitytrader.com offers a refund of the monthly subscription if the calls don't make money. The one problem I have with that, is that if it gets to the last day or two of the monthly cycle and if the calls for that cycle have not made money, there may be a temptation on the part of room leader to swing for the fences. If they know that they are going to lose a whole months income then it would make sense to try and make up the losses in a day or two, with the possible outcome of putting more than the monthly subscription on the line for the members. Apart from that, it seems like a genuine effort to give a guarantee of sorts.
