Alrighty, Im gonna purchase a domain from an official emercoin domain name registrar. Do they sell .emer domains to corporate entities?
We don't have domain zone *.emer.
Instead, we have 4 zones: *.coin *.emc *.lib *.bazar
You can "buy" domain in the any of these zones. See document for details: http://emercoin.com/EMCDNS_and_NVS
Regarding "sell domain".
We (developers) do not sell domains. You can allocated domain yourself, using EmerCoin wallet.
Just install wallet, take EMCs somewhere (for instance, buy at exchange), and "buy" domains yourself from blockchain.
