I'd probably be one of those Anonymous donors of money, as if you publicize your name, you suddenly get 500 new "friends" and hear from family members you have never talked to.
There's a dude up here in Maine whose been giving his money away like crazy. Except his name is on everything that he gives away, which kinda gets tiring. You'll read in a newspaper " such and such place gets a donation of x amount of money from Harold Alfond and his wife 'Bibby'". I think now every college in the state has at least one building donated to them by Alfond.
As for coming into money, I've got two trust funds in my name. Once I finally resolve the issues with my dad being the trustee, I need to get a Will drawn up, because if I die, the money goes to him. I have no real use for the money, so I haven't decided if I'm gunna donate it. My immediate family are taken care of.
