Hi I have looked at your site what a brilliant idea :). I see what you mean about only a short content area. Have you considered a Facebook group or page - you could add a link to it from your site this would allow space for further comment suggestions etc. Have you considered giving the companies/sites using your marketing tool the chance to buy a 'visa' that allows them to link to another area on your map and also another website offering similar subject matter. Gives you the chance for further revenue streams along with helping each subscribed site to purchase further links in the form of visas. Please let me know how your site progresses it really has terrific potential Laperegrina
