Customer service is serious business.
Please note, currently there's a huge backlog of "I want to be a dealer, please tell me how much for 6 boards", and other similar requests filling up the email queue, so unless your email is deemed important, it may not be answered immediately.
The email form DOES work, so re-sending another email 24 hours later asking if it was received is counterproductive - it WAS received, and may be answered in order.
