Sounds great. I'd be happy to pay for some ideas, as long as Ryzom devs confirm they include said idea in the game once it's fully developed. How about a bounty system then? Or like a feature 'kickstarter' where a player can post an idea and other players can pledge towards getting that feature coded. The first individual or team to complete it collects the bounty or pledges.
The code could be run through Ryzom Core and thus public and peer-reviewed to prevent bad ideas and poorly coded features from hitting the live game.
