This question is really a follow on from a discussion in another thread in the TGP forum.
If all of my out links from a free site go to a pre-sell page rather than to the sponsor (and the sponsor doesn't object), would you be reluctant to list the site?
How would you feel about any changes to that page, assuming that the new page didn't break any rules, and it was monitored by the sponsor?
Here is an example of a pre-sell page, and the sponsor is aware that I use it in this way.
