I was a little cautious about publishing those figures - and I was quietly pleased the thread dropped quickly. But as it has been brought up again, I shall comment.
I do have some way to go to make this work fulltime. Our costs grow as user numbers grow too - I don't want to go into details, but we started this service on a $199 a month machine, and I can tell you, we now have 2 (way bigger) servers that cost many times that now...
But, given time, if people continue to support the site, we will get there.
Regarding donations, no one should feel obliged to do this.
BTW : Don't read the above thinking the site is in financial difficulty - nothing will kill this site short of everyone terminating their subscriptions at the same time!
