I know of a group that I am currently in that they hosts a bunch of raffles (like over 5-10 a day, we dont have to host many a week), and they host things from AK-47| Redline, to things like a Karambit Boreal Forest, and their entry prices vary from like .50 (a not so expensive gun) to a key (2.50, for something like a knife or something of equal value) and the slots in the giveaways get filled up quick. If we did this system we could bring in players to the forums to sign up for them and increase donations.
