my idea, if there have to be ads, make it on the ufsg, and make it voluntary for fs - put it as a changeable preference, so if you ahve it on you get a certain number of fsp each week. if it is on, it will replace the bottom banner?
If there is FSP offered for it then it should be something along the lines of every 30 days they log in and witness the ads they receive 5 fsp or something like that or some kind of tally system that has a bulk pay out instead weekly other wise it will change the fsp market too much.
Maybe make the 6 month deal for people doing free offers but anyone donating their own money should have at least a year
