Most of these pages are less than 5k total.
This one page of this thread right now is over 14k.
Lets say I was really busy and went through 700 pages on that site today.
700 * 5 = 3500. That'd be 3.5mb.
For reference, my web host charges me $9.95/month for over 1terrabyte of transfers. If my math is right, that could support almost 10 players per month. If 2 of them did a donation pack then the bandwidth for that month is paid for.
I dunno, maybe my math is off or something, but it really seems like it could be turning a profit easy.
