One of my friends is in our geek town now - http://geekswithblogs.net/faf/Default.aspx
Łukasz Olbromski is a leader of one of the fastest growing .NET user groups in Poland - Wrocławska Grupa .NET. This guy is a working hero for me. He does at least twice as much as I do in Krakowska Grupa Deweloperów .NET. I believe he would have a lot to say about building community and managing a set of volunteers.
We are organizing Heroes Community Launch together. I'll post about that soon in more details. We have big plans in this area.
