I can't say enough good things about DNSimple (and I've had lots of bad things to say about other registrars). Are you guys still reselling enom for all of your TLDs? Pretty please will you get your own setup for at least .com/.org/.net addresses? And when/if you do can you make a big stink about it so I know to transfer all of my domains to you guys? I'd love to give you more money...
I can't promise I can do it, but I'll work on it. ICANN accreditation and registry access is all about money. If I can get the working capital then I'll get DNSimple accredited in 2012. Believe me, I'd love to be able to do it.
