Bulk Register and Bulk Transfer
This feature can be useful for those who regularly register domains for their clients, hosting providers, companies that promote web sites or create satellite sites. A list of domains can be put into a special box and checked with a single click.
There is no much difference between bulk registration and transfer comparing to single domain registration and transfer. The only thing needed - a list of domains and, in case of transfer, the list of appropriate EPP-keys. See Domain Transfer article for more details.
