I thought it would be great to not let many of the interesting side projects done by developers, entrepreneurs be abandoned like so many, but let them find home in the hands of others. It's early days and we are learning and figuring out our ways.
The Help/Support feels a little buried within the FAQ section - "support" is in the menu, but Seller's Guide and Buyer's Guide seem important, and I wouldn't have thought to look under FAQ.
Also when money is involved, even if you're clear about not handling the monetary exchange, I tend to look for an About, or more concrete contact details. Favorites icon would be nice, too.
Hope you gain great traction with this project!
