Ubuntu-GR Team contact change

[Giorgos Logiotatidis]

Hello,

It is time for Ubuntu-Greece [1] LoCo Team to change team contact. I'm
happy to introduce to you Michael Kotsarinis who will serve as team
contact from now on.

I was the team contact since the creation of the LoCo team in 2004 and I
gladly served all these years one of the biggest floss communities in
Greece. I would like to thank everybody for the great collaboration and 
support.
