What cash system is this?

[Rob1986]

I'd like to implement this real cash system to my forum.

Is there a hack for something like this or is this a custom hack? You can see the amount the user has earned in their postbit. http://www.mkpitstop.co.uk/forum/78549-post9.html

Is it possible? I'd like to add something like this to my forum.
