David hasn't been around in more than a year (health reasons I think). LadyHawk has a separate PayPal for the site which Ning is authorized to access. So rest assured your donations go to WN. (I tried to investigate the funding situation but all the many of passwords LadyHawk shared with me over the years don't work, but when I was on LiveChat last night, Ning said the site was in good standing.)
Thanks for letting me know that you're having problems with the site (you're not the only one) I think it's a Ning problem and I have a couple of ideas but I think it's time to contact the creators group over there. You contacted our administrator - LadyHawk? She hasn't been on WN in over 2 years. I'll keep you posted on what's going on.
