It's not something that I've ever done......because my thinking is this: Nobody gets inundated with people asking them to make a forum. The owner chooses to do it for whatever reason.
So if they've chosen to do it.....should everybody else have to dip in and finance it? It's like you organise a rideout with a bunch of people then expect them to pay for your petrol.
As I've said before, I have virtually unlimited resources available to throw into this place. And nobody else is in that position. But even if those resources didn't exist then I'd still carry it myself!
Also.....if people have financially contributed to a forum then they have a right to expect something from that.
But with no contributions, nobody has a right to expect anything! And I do my best to ensure that I meet that expectation!
