I am also still waiting for 2 $5 rewards since June. I doubt that I will get either of them. It seems the site has been abandoned, and there isn't anyone running it.
I play a few games each day, just for this reason. I know all points in your account are forfeited, if you don't earn points for a certain amount of time (30 days?)... but I think I remember reading that pending rewards are also forfeited when an account is inactive.
