you provide time and location of the last encounter with another person you're looking for (e.g. yesterday on Piccadilly Circus, London)
next you give a short description of yourself and the other person you're looking for
this search profile will be stored within MetU's database
as soon as any match occurs (i.e. there's another person matching your description, that is also looking for you via Metu) you'll be notified via e-Mail
contact information of both of you will will be exchanged, i.e.
- (a) you'll be noticed and get the e-mail-address of the other person and
- (b) your e-mail address will be sent to the other person too.

Missed to exchange contacts ?

With MetU now you get a second chance!!!
