Actually, I think we should have the raffles set up with a little tweak: entry could be allowed based on the activity of a forum participant.
If you have someone participating a lot, that could gain him more entry chances.
On the other hand, the guy that says nothing and contributes nothing could be very limited in how many entries he'll get.
This could also help some brokedicks -that need a nice raffle win- to post more and drive forum numbers a bit.
Of course some "deskriders" could be limited also.. Yeah Doc, I'm lookinatya!
