I'm in the process of starting an online community that will run off of virtual currency (credits). I want the members to be able to earn free credits by completing certain actions and also be able to purchase credits via paypal. My probelms (which are big ones) is understanding how to implement a tracking system that will track a user's credits, automatically recognize when a user is out of credits, payment gateway, and also I need to understand how to get someone to use their credits to download/upload a video to their ipod. I know this is a lot of information to digest but I'm just starting this idea from scratch with a web designer who lacks a lot of programming knowledge. Any ideas would help even if it's directing me to websites or hosted solutions that could solve this probelm for us.. Thanks
