Just did a quick count of names listed on the e-mail address log. Looks to be about 3700 +/-. Of course, there were fewer whose monikers I recognized.
As a non-profit, the Mudcat could develop membership rankings. There is the basic free membership. Then there is the $35 membership. For a $60 pledge, you get a Mudcat T-shirt. For a $100 pledge, you get a T-shirt and a CD of your choice from a Mudcat sponsor. For a $200 pledge you get a T-shirt, a free CD and a Bill Sables guitar strap. For a $500 membership you get all that an a possum ocarina from Barbara.
Hey, this sounds like a concept to me. It works (sort of) for Public Radio and TV. And we probably have more viewers than some of those stations.
This obviously requires a little more administration and bookkeeping, but I think it has possibilities. Then each could give according to their ability.
