you can send money to Meagan's commissary account! that helps a lot because it can pay for toiletries, medications, the stamps and labels she has to buy for sending letters, and snacks*! Unfortunately the payments have to be made to her deadname :(
The link above has the methods for sending commissary money, through MoneyGram, Western Union, and USPS money orders. For all of them you have to use her deadname and the registry number for her, which are:
Bradford Winston Morris, 11136512
The account number you send money to (for MoneyGram and WU) is going to be 11136512MORRIS.
if you have any further questions feel free to ask me, I have experience with sending payments already.
*Meagan tells me that the breakfasts at FMC Fort Worth are godawful grits, plain bran flakes, or plain oatmeal, so snacks are kind of necessary to make sure she's getting something decent to eat before lunch and dinner. The lunch and dinner tends to be weird but at least better than the breakfasts, which are uniquely bad.
