Paid to promote means getting paid for promoting a particular website right?...Ive joined no-minimum and wanted to try their paid to promote. They have given a list of accepted websites to promote their link on. But I simply couldn't find a place where i can actually post the link? How does this PTP work?

You can promote it in ShareAdspace.com (a traffic exchange)

Or you can promote it any other PTR's manual surf page (country targetting may not be possible)

Simply go to the redemptation area, click the link associated with PTP advertising(the link won't be clickable until you have enough money or points), copy and paste the PTP link you want to promote, type in the description or the like, all done, the rest you may want to do is going back to the PTP part of the programe you are promoting to see how many credits you've collected up to the moment. Good luck.

I think there is a bit confusion.

You are talking about redeeming for ads, whereas the OP asked about using PTP of no-minimum.
