re-selling process at a lower price is a very effective way to find the optimum cost of the books valuated by the purchasers.
It can foster resources sharing and encporage people to upload more and download more useful information.
I think sharing is the aim of this forum. this forum is non-profit making anayway.
Agreed with previous posts, let the market determines the cost of purchase and preimum of uploads.
Given that there are always downloaders who want the information, this re-selling process will not prohibit uploaders from uploading new information.
Coz the money uploaders making are not real money but juz a medium of exchange within this forum. And the desire of the downloaders in this forum obviously is not unlimited. So the free rider problem will not give a big hit. by the way, the first uploader is free rider to the author of the books anyway. So, they have no rights to claim ownership of the files.
