Supporting Membership

Normally, we collect Thanksgiving Science Fiction Society (TSFS) membership dues as part of Chessiecon memberships. In year without a convention we rely on Supporting Memberships. A TSFS supporting membership is $21.00 per year. The 2024/2025 TSFS supporting membership year begins December 1, 2024.

Send your name, mailing address, email address (optional), and $21 using any of the following payment methods:

  1. PayPal: payments@chessiecon.org
  2. Square: Email your information to registrations@chessiecon.org and we’ll send you a Square invoice.
  3. Personal check: Payable to: TSFS. Mail to TSFS, PO Box 83032 Gaithersburg, MD 20883-3032
