Hey! I am from Novi Sad, Serbia and it would be really unusual and interesting experience to meet someone from this kind of ''social networking'' web sites.
As a member of (so called) biggest European Student organization - AEGEE, I travelled a lot around Europe, and met many new people and made friendship from various nationalities. I was so often a guest but also a host.
For some reasons, Novi Sad (2nd biggest city in Serbia) is not on the available list, so I put Belgrade instead.
