Check the domain(s) (on the left) that you wish to "push" and then select "Change Account", I believe ... you then have to enter the recipient's Whois information / GoDaddy E-mail address. :talk:
These "pushes" at GoDaddy are not as easy as Enom, NameCheap, Dotster, Registerfly, etc., but they work okie, IMHO.
Best!
