What is ucash / ushop?

Everybody seems to be using ucash / ushop, but what is it? I can't find anything about what it really does.

Can someone explain or direct me to a manual. thx...

Ucash is a system where users can gather points by posting on the forums. There points can be spent in the Ushop. The Ushop contains things that can modify the username appearence. Like a bold username, a different color, outer glow etc etc.

Its mainly just for the fun of the forum

I want to pay money to my users when they post. For example, 5 cents per post, not point or games or whatever else. Users are paid when they reach 100 posts let's say. That's the only functionality I need. Will this Ucash work for me?
