Could anybody list which companies will register domains for your site. (your webhosting company) and let your users manage it from your site. So they would give you a API script. So far the only company I heard that does this is bulkregister.com. Which other ones.

the biggest two that I can think of are:

http://www.opensrs.net
http://www.enom.com

I know there are more but those are the top two I can think of...

any companies that offer this service without any startup costs?

http://ir.dotster.com

I agree. I was looking at Dotster and they look like the best.

Dotster is defiently the best one out there! No questions about it!

I have also heard about http://directi.com and http://onlinenic.com.

Anyone has any experience with these two companies...?
