If everyone of those users who is a regular donates just a small amount then this website would run well and we wouldn´t know how many users there are because we wouldn´t get =that= error message.
Unlikely that one very rich person is going to suddenly donate $10000 but if 500 of us gave $10 that would be .. um.. uh .. like, say more than fifty quid or maybe like ... a hundred or somethin´. Anyway, hard maths aside, $10 is a lot less than most of you losers pay for sex on a Tuesday night when your ugly old wife is at her sisters.
