Great that it helps! re 1) Ok, makes sense. Will be tough though. Margins will be very small. re 2) I get the wantlist and how you wand to 'collect' demand, so the suppliers then will follow. But I'm not really convinced the users will actually follow through. As long it's just one of many features, that's fine. But make sure you don't build your business model on that. re 3) Change that. Otherwise it won't be used :p re 4) Don't know if I misunderstood, but what I meant with Facebook is not only as a trustbuilding method but to just replace this page: http://comicswap.com/login http://comicswap.com/login Completely. (Yeah not really, there are still people not using FB or not trusting you with their login, but I think it would make sense to make FB the default, and then under a ---- or ---- offer the normal forms). Then you even don't have to make them connect to FB for trust-verification-reasons as they already are. Just a thought I got while writing: Thought about offering (parts of) your platform as a whitelabel shop for local comic stores? So they don't need to create their own web shop, but can just use your, specialized platform?
