Mailed off DVC form, no confirmation?

[lenshanem]

I sent off the DVC discount forms for RFTT and my check has been cashed, but we've gotten no confirmation by mail or email (They was a space to put our emails in.)

Do they usually send back or email something?
For the 5K DH did last January he registered online and was getting emails often.

For the Minnie, we never received any confirmation email until the month before the race. If you have a cashed check you are in.
