Can I introduce WhentheMeetiinsOver.com, a website aimed at the business traveller. We link people travelling to the same city at the same time. The site is free to join and members email exchange about the best places to go, eat, shop, sightsee, play golf/tennis whatever.
It also has a live forum.
How many times have you been in a city and you're not sure where to go or what to do after the meetings are over? And you'd like to talk to others who are also travelling? WTMO allows you to do this.
