Plenty of travel bloggers have built something beyond the blog: a course, a planning tool, a spreadsheet template, an ebook. This is a catalog of those things, for members who keep a resource page and would rather recommend something made by someone they can actually reach.
Nothing here creates an agreement, and there is no reciprocal link. A member either finds your work useful enough to put on their resource page or they don't.
That also means it isn't monitored the way swaps and chains are. It's a catalog, closer to the member directory than to the marketplace.
