I'm not sure if I understand the concept of reselling a domain.

Do you mean that it allows you to put a domain from your portfolio onto auction like eBay, or does it merely allow you to sell your domains more easily and create a simple transition from the original owner to the next owner?

Reselling a domain is just selling a domain that you own. It could be on a auction or just advertised here on NamesLot.

Once the domain has been sold and paid for, you can usually "push" the domain into the account of the buyer if it's ad the same registrar and there is generally no fee for the push.

If the buyer has an account with another registar, then they will have to put in for a "transfer" and pay a one-year registration fee which is added to any existing registration time on the domain.

Sorry, they are called "reseller" accounts because the company that you sell for is the "seller". And in this case you can just sell the domains anywhere, but via a specific site.

Oh, thank you for the information.

I may use Dotster in the future, as I am a United States citizen - I am wondering whether or not the potential buyers would only be a United States citizen, though. That would sound like it would cut the potential buyers down by a vast amount.

I think the restrictions are on the resellers, not on any of the buyers of domains.
