I have been searching google for hours for a program that will allow users you upload and download files from a server. But have advanced administrative options. Such as a point/credit/token system. Which means a member buys lets say 100 tokens for 10 dollars. The tokens can then be exchanged for electronic goods, files, images, videos, etc. The closed program I found was something like 500 or 1000 dollars, which is more than I am willing to spend on my project. Prefer it to run on windows, but linux is fine too. Ideally be integrated into paypal so members can get their points instantly after paying and begin using them. Thanks.
