As of a few minutes ago, DNSimple is now providing domain registration and transfer services to all of our customers. We've had customers testing these two features for the last few weeks and so far the response has been awesome. The goal, as always, is to make domain management as painless and hassle-free as possible, and I think we've done that.
To register or transfer a domain simply use the Add Domain button and check the "Register or transfer this domain" option. The first time you'll need to fill out some contact information, but on future registrations or transfers you can easily just select your existing contact info, or add new info if necessary. For transfers you will also need to follow instructions that are specific for each TLD. It's less than perfect but there are some things even we can't make simple.
And for all of you Silver customers, you can now have up to 10 domains before you need to upgrade to Gold. Thanks for using DNSimple and please tell your friends about it.
