The Cost of Custo

just a question i thought i would ask, i searched previous threads and couldnt find anything relating to this so...

How much in any currency does it cost to run custo?
How much is generated off the popups?
Since the servers are obviously quite taxed, what kind of expansion is needed?

im willing to bet that custo if it asked for money, would recieve it. The community is loyal enough and the service valuable enough, that i think if custo asked for donations (no required membership - art is free) it would be possible to infinitely increase the service to the skinning community.

just a thought.
