FWIW - I didn't view this as a popularity contest. I took it as stated in the OP.
My only nit is that I'd like to see at minimum a url provided so that we know which charity specifically is being asked whether to be added to the list of FT charities. As scoow pointed out in his post above w/ links to dif ones, sometimes there are similar-sounding charities.
Given that FT has members from around the world I see no reason to limit charities only to US-based ones.
Cheers.
