Virgil,
A quick suggestion on the membership fees.
Add a page to the web site (maybe it’s already there and if so I apologize for missing it) so that WTA Membership fees could be done electronically. Use Paypal and if they charge you for it add that as a service fee to do so electronically. Printable receipt/record for proof of enrollment at various shooting events.
Could also use a similar page for home-grounds donations.
