I just think it's good practice just to have a release and you can do that pretty easily if you have some printed off and when someone what we do, is we email a student a form if they want they can email it back to us, and we make sure it has a notary on it, just so we kind of have a little bit of proof that it was the student that signed it and that's not a burden to anyone who wanted a reference, because most banks and places have the establishment of the bank that a lot of them will just do it for you, so i don't think that's a big burden on anybody.
