This might be a crazy idea, but what the hell.
What if DLD gave members the option to either pay for membership or get free membership, provided they PROMISE to pay for each gain they get. For instance, if you gain half an inch length, you pay him 50 dollars. One inch, 150$ and so on. Girth gains are more valuable imo, so 100$ per half inch or something
Ofcourse, you can't expect to get everyone to fess up to their gains with this scheme I guess. But, if only 30% paid, I think there could be value in it. Could also be something that would be offered to respected posters
Just a thought hehehe
