I love the idea of this site. The only thing is, you gotta make it more user friendly. Make it sooooo easy.
In my opinion, it give the "average user" too many options.
"Import to wallet"- medium to hard difficulyy for average user
"instant", "list", "csv"- average user doesn't even know what that means as far as bitcoins and wallets, etc. are concerned.
And the costs, and amount, and donation, you might want to specify is that in btc or usd.

Is it possible to just have the user type their message, then say send x amount of bitcoins to xyz, and then your service automatically sends the funds to the blockchain?
