I would be happy to pay for a paid version. I don’t believe there is anything else like this in the market right now…at least for BuddyPress. I say, come out with the new release and charge people for it. With nearly 20,000 downloads, a number of them are sure to upgrade. I don’t think there is any problem with charging people for your time/effort. I look forward to further development and would be willing to pay upto $100 to see some of the functionality that’s been discussed. Otherwise, I would like to know what you would charge to get some functions added directly to my project.
