No. You only need to worry about providing the points you offered to the supplier.
The person who supplied the item will PM the file to all the people offering points and collect points from them. The person who supplied the item has first dibs/priority on uploading it to the site to share with the community (this way he/she can be rewarded for more points from downloads).
Normally the supplier will request to have the thread close after all the points are collected.
