I Emailed the treasurer (contacts for board members) for you, but…
Did you select the Deluxe package? I was tempted… Help for glider setup and breakdown (once per day), walk to the head of the queue when ready to launch, other pilots will clear the thermal when you arrive, and you can land on of the full width of the LZ.
The Platinum package (3x basic membership) seemed a bit much for me: Only adding cold beer (up to 2/day) to the Deluxe package.
