Some people help others, others help themselves.
Erik is the former not the the latter.
Erik is gracious and is not greedy. The little bit of energy he gets from his members, memberships and the like, hardly equals the energy Erik and workers give back.
I kind of already gave a donation to chess.com. I recently paid for a yearly diamond membership but soon after decided chess was beginning to fry my brain, and closed the account. A bit of a brash move... probably should have just finished my games and took a break. It's a couple of weeks later now and I'm back playing again on this new account and heck I'll probably buy another membership soon. So it'll be 2 memberships for myself in a year. Bleh I'd rather give my money to chess.com though, something I actually enjoy, than send it to some ambiguous non-profit that is probably corrupt anyway.
