If you have a website that is London based or sell services or good that are unique to London you may suggest your site to the appropriate category in my London Directory. You do not need to link back to the directory if you suggest your site to one of the empty sub categories. I am quite particular about quality of description of your site though, it must not be less than 80 words. Feel free to suggest your site using the premium listing, exit at the payment page and let me know and your site will be approved. Thanks
