Hi Vesna, and welcome!
I think this is a good opportunity for all of us to introduce ourselves, as this list is growing quickly!
I'm Jenny, working out of the Sudo Room hackerspace in Oakland. We're in the early stages of building a mesh network, the documentation for which can be found on our wiki here:
http://sudoroom.org/wiki/Mesh
My background is in Anthropology and Communication, and with regards to the mesh project I'm most interested in the documentation and community education & outreach components - though I'm enjoying learning about the hardware and software aspects of building a network, also :) For money, I work at a startup called Open Garden, which has created a free app for sharing internet between mobile devices.
I was just in Berlin for the International Summit on Community Wireless Networks, where we had some great discussions on developing a Network Commons License and Free Network Definition. After this week, I'll have settled back in at my home base and will contribute more to the conversation.
Would love to make it to 30c3 - do they offer travel scholarships ever? ^_^
