Hello,
How do I leave feedback for a forum member without having a link to an ad or having to enter an auction number? There was no ad and there was no auction as the sale was conducted privately via a PM.

Thanks,
Shawn

Feedback can only be posted for transactions that take place through the marketplace. The buyer must post an offer using the Make Offer tool in the ad and the seller must accept the offer through the marketplace. Unless these steps were taken, feedback cannot be posted as there is no record of a transaction taking place through the site.
