Everyone who joins the forum starts out with $0 and earns money through participation in our stuff.  I did this so that there would be a point in doing the stuff, rather then have it be a calculation of experience where everyone d90 and above has the same enhancers / etc.  Right now since it is at a starting point it is pretty much for doing matches, although I plan to implement more ideas and ways that people can be active and earn money, including more RP oriented activities such as crafting, etc.
 
You can transfer money, if you decide to give away what you have earned for whatever reason.
