I transferred tonifamulari.net to my account yesterday. The transfer went through and my credit card was charged. I expected to see it in "manage domains" but it does not appear. It is resolving correctly (it points at a subdomain.) By the way, I'm very happy with the speed of the service compared to Yahoo hosting!
It does appear that the registrar has already taken control of the domain name. It is still showing as pending in your account. This is not unusual as the registrar sends out confirmation emails to our system at specific intervals. Once received, it should automatically move it to your billing area and be available in the "Manage Doamin" area of your AMP.
