I think the point of her request was that you don't always know who made a character sheet, and there is no interface to bring that info up for sending gifts to them. If the creator of a sheet doesn't put their roll20 user id in the json file(i think its listed as optional) then you may not have any way to know who it was. Even if they do put it in, roll20 doesn't add anything that can definitely be linked to only 1 account in the info for the sheet, so you would have to look at the json on github, then search for that user to gift them.
