OK, here's the deal if you're on Dwolla.
We don't have any way to contact you, because Dwolla doesn't tell us. That's the nature of Dwolla, and that's fine.
We're forever grateful for your ongoing donations because we could not keep doing this without you. And we'd love to give you the bonus content... but we can't without knowing just a bit more about you.
So, I'm putting together a completely voluntary register for Dwolla donators. I'll let you know soon how to enter your details, if you're interested.
