Sorry for the cross post but it appears not everyone is reading both threads:
In an ideal world here is what I would like to see:
Button [Donate through JustGive.org] we only get 95.5%
Button [Donate through PayPal] we only get 95% (or whatever the real number is)
Button [Donate using Bitcoins] we get 100% of your donation!
OR Donate using Bitcoins to 17gN64BPHtxi4mEM3qWrxdwhieUvRq8R2r and we get 100% of your donation!
this is not entirely true though, they get 100% BTC but then when they need to exchange it to USD or what have they there will be some % sliced off of that
PS folks, don't focus too much on publicity, otherwise it sounds like we're bunch of desperate telemarketers. good deeds will find their way into publicity by themselves, no need to make it in to a goal.
