Hi,
Currently the method of choice for nop-commerce voting is one vote per registered user of codeplex. Votes are important cause they signal dev team what is more important and what is less important.
On the other hand there is the "community sponsorship program" which sucks because the main benefit is that you get a lame avatar instead of the cool one you already have ;-)
I've been thinking what would happen if people could not only vote with your one vote but also buy more votes for cash e.g. $3 / vote? This way NopCommerce would generate some revenue and (maybe it could get more hand on board so things could go a bit faster) and the users who are in need of some features and are willing to pay for them could do so for the benefit of community.
