Please help me understand this email from NameJet about my recently acquired domain.

Please help me understand this email. A domain was backordered with Network Solutions, I acquired it when it expired Via NameJet.

NameJet's email to me says "The next step is for NameJet to add the name to the appropriate account for you to manage at the sponsoring registrar. This can take up to 7 days (slightly longer if the domain is a private sale and a transfer is in process). You will receive an email from the sponsoring registrar with login and account information at that time."

I have No idea what this means.

Will I be able to add this Domain to my Godaddy account?

Who is the "sponsoring registrar"?

Am I stuck with Network Solutions?

Thanks!
