Nick,
This is a suggestion and requires no answer.
I belong to an experimental aircraft building forum of 5300+ members. Every year a gentle reminder is posted requesting members to donate to support the site. The rational is that this particular forum is the single biggest and possible the only source of information to build a fabric covered biplane. Pretty much all the biplane building expertise on the planet is on this site.
Members do an excellent job of supporting the forum. Monthly, yearly or lump sum donations are the choices and they go through PayPal so it is almost painless.
Your forum has a lot in common with the aviation site as it is the single biggest source of kayak building information on the internet.
The information I get here from you and your membership is better than going to college. I for one would be glad to donate to the Kayak Forum web site . . . . . . . especially if you sent me a sticker to put on my truck window - - - free advertising :))
Thank you
Randy
