I'm the founder of MeetingWave (formerly TravelersTable) which is a free networking tool that helps you connect offline with people you want to meet in the places you will be-- whether traveling or near home or work.

Successful business people understand the value of face-to-face meetings. An in-person meeting creates a strong and lasting first impression, particularly when you’re developing new contacts. MeetingWave focuses on developing your business and social networks through face-to-face meetings. Meetings can be arranged for purposes of social networking, business networking, sharing common interests, or any other purpose.
