daymn theres a whole bunch of f***in n00bs on this bithc. Do NOT NOT NOT NOT do anything that involves interpersonal contact, like you asking or having your friend ask or looking at IDs, waaay too much potential to have ti go horribly f***in wrong and leave you out there without guidance from savy letsrunners like your boy jagerbomberjacket. Here are the good ideas so far
(1) ask for her email, this is money for real, her email likely involves her name, if it doesnt send her something and when she responds you could get one back that has her name either with her address or in a signature block, and if that is not the case then you can go look her up by email on facebook.
(2) if you know where she lives, go look at her mail
(3) use reverse phone number look up
(4) Call from a blocked number and hope for voicemail
Dont take any other suggestions, doing any and all of these will get you your name, when you do, report back and let us kknow
