I too use a PO BOX... and it's BUZY... I keep all my sponsor payments, etc going to another box in the same office, however running freehosting, we get a ton of legal C&D's, etc etc for different sites that get set up.. (never mention Adiads, Marborro, YMCA, PokE'Man (yeah, man), etc on your sites... i find generally they are gay sites, aparently corporate america doesn't like homosexuality tied to their products).. so thats why we need the actual address to check for stuff
The only problem I have is that my PO Boxes are back in washington DC and I'm in southern california now
hehe... oh well
