I just have one thing to say, don't bother, go to GoDaddy www.godaddy.com
Dotster's support sucks, and the reseller they use for DNS maintenance (that they charge you $15 a year to use) is FREE at www.mydomain.com
When dotster implimented domain locking i didn't sign up for the service for a few of my domains, so they were locked at the registry level. In order to make changes to my NS entries I had to write into support, wait 2 weeks for a response, and play email tag for an issue that i could have updated myself in 3 seconds if it weren't for the lock (that I never signed up for in the first place).
In all reality their prices aren't even worth it, theres better registrars with better services and cheaper prices.
