I'd be nice to have a place on the website that shows what games buyers are looking. Buyers could let the sellers know what they are looking for.
Buyer's can request notifications on any item on the marketplace that isn't in stock right now. There is a 'notify me' link on each product page (see example)
We don't have any tools made yet that let users see what other people have requested. I'll leave this open so users can vote on this feature idea.
