I work for a hosting company in Europe offering a range of
Linux/BSD OS's on dedicated servers.

Right now we are about to add Debian as one of our offerings on our
dedicated servers, and I have been giving the task of finding Debian
sites which appeal to our target group, which are technical skilled people like:

1. Programmers
2. Engineers
3. "Nerds"

I would like to have the most visited URL's of narrow community sites
(preferably in Europe, but not mandatory) who share a stong interest in:

A. Primarily Debian.
B. Secondly Linux distro's in general (like the site http://distrowatch community).
C. Thirdly the Open Source communities.

Also I would like the sites to be offering either or both:

II. cheap banner ads for our announcement of Debian
III. accept of publishing our technical based press release

I am not interesting in forums as they to my knowledge do not accept
II and III.

The information needed is urgent as I am behind my schedule...

I am prepared to tip you generously, when I get my useful URL's.

Thank you very much in advance. I am looking forward all answers, and
comments, as I am a newbie to this Google service :-)
