Well, I keep everything free at my site, I have one button at the bottom, that says, "Help the site stay alive". The users contribute, they don't know there are benifits, well most of them don't anyways, and are really greatful, they have donated much to the community, when we were in need. Which of nothing I asked (seems sort of rude to ask

)
When someone helps me, I like to help them
Only few days from now, I will be taking my Contributing Benifits Program Public
