If you want to wish Ben Happy Birthday, here's where you can do that yourself, at happybirthdaybenedict. Go look in the archive for inspiration too, before you create your own message to Ben.
You don't have to be a tumblr user nor a native speaker of English.
You can write text, do a picture, or a video; just please keep it brief so he has a chance to see them. Please!
Just get it in by 18-July... the day before Ben turns 37. :D
If you wanted to donate to the birthday charity Ben chose, it's here. Thanks to Lokke, whose tumblr gave me the details... and the groovin' socks too!
