Hi

i am now going to register my first domain on resellone

how to get my From Previous Order Order ID ?

from ev1servers?

Just register it as a new account within the RWI when you add the domain in the place "Place Order Manually: " field, you will then enter your information in the "Registration Type: New Domain Registration " fields and completed from that portion down. You want to do this everytime you set up a new account for your EU's.
