Merhaba Nikolov :) I would have been glad to meet you, but I stay in Ankara :( I think you are on graphical prject in Istanbul. Which company works based on 3D environment and simulation on Istanbul?
Nice to meet you. Saygilar :D Ümit Uzun 2010/1/15 Trajce Nikolov <[email protected]> > Merhaba Umut :), > > its the google mail stuff, I guess based on the ip.
