I agree. It’d be really nice if you could get a badge for rating items you’ve purchased. Out of all sales made, only a very small percentage of buyers actually come back and rate the item. Item ratings are of a huge help to authors and it’d be great if there was more incentive for buyers to rate their purchases.
WordPress Plugins from CodeCanyon are GPL , and that’s specified in the license that comes with the purchase, so don’t worry about that part.
Jeffery, I think it’d be a really good idea if the Code Canyon people (all of Envato actually) rethought the GPL licensing of marketplace items. The GPL is a horrible license and would allow someone to buy an item, modify it, and redistribute it.
Just a thought.
