Too bad Folio doesn't send email confirmation to let you know they got it. I can't help but think I'm gonna wait the six to eight weeks only to find out they never received it.
Did you snail it? Next time just mail it w/delivery confirmation. Meanwhile, you certainly could email the assistant and let her know you accidentally neglected to and could she confirm rec?
If you emailed it, do they specifically state they don't confirm? There's nothing wrong with asking if they could, if not. Granted, they may not answer, but you can ask.
And good luck on your full.
