At some point in either late March or early April, the Contact Us form on the site became corrupted. It may have happened during our site upgrades in Feb-March, which also included email upgrades.
So we may have missed your important emails.
It went by unnoticed because
(1) It's the slow time of the year anyway.
(2) All other forum generated emails were working normally.
Please re-send any inquiries, and we'll be sure to answer. This issue has been resolved.
Thanks to ridzoman for PMing us about the problem.
