thanks for the welcome to Joerg!
As this is my first post I'd like to introduced myself to you:
My name is Vinzenz Vietzke, I'm 26 years old and live in Augsburg,
southern Germany. I am working as educator/pre-school teacher.
My first (unsatisfying) contact with Linux was in 1999 with Suse 6.0.
Since 2006 I'm using Linux as preferred operating system, starting with
the unavoidable Ubuntu. Moving to Debian a lot of distributions
followed, ending up and staying for a long time at Archlinux.
Since mid-2010 I am "fedoraised" and now want to involve myself into the
I've been working on various Linux and open source projects, especially
on maintaining packages for Archlinux, translating Debian packages and a
lot of different tool on Launchpad. 
As I'm a pre-school teacher my abilities in conversation, explaining and
training would be useful - not least for grown ups. :)
Hopefully you got something like a approximate idea of me and my
efforts. If there are any questions, don't hesitate to ask me!
