I do have 100K friends from London, and 50K more from other parts of UK. I can segment these friends on sex/age/city and deliver targeted invites to page/group/events within minutes. I want to trade invites with UK friends, and I would be potentially interested in Germany, Spain and Portugal friends too (I do have additional big databases to trade with in these countries). PM me if interested No exchange for USA friends by now. However if having a very large and stable USA database PM me for future exchange or for sharing growing techniques and database development tips.
