That would be nice, but since anyone can register under any name, it's possible that someone unrelated to the vendor could register with the vendor's username here on the forums. Plus, in order to make sure that a vendor isn't a scammer and isn't LE, we require 35+ transactions of selling illicit goods/services on SR before letting a vendor into the Vendor forum. If a vendor has 35+ transactions, all that he/she needs to do is send a PM to inigo or one of the other admins and ask to be let in. The admins will then make the decision.
