Hello Jan,
Thank you for your great words and encouragement. I really believe that the more chapters take part, the more chances we will have. Since I am a member I am currently convincing WMAT to join the Transparency Register, since they could put me on the list to get access to the Parliament (daily passes and the like). Since I am currently involved in the founding of WMBE, people here are quite enthusiastic to help. They have contacted WMNL.
I was lucky enough to attend a Creative Commons Belgium Relaunch event in Brussels this weekend. The CC people (a law professor from Namur specialising in copyright and a law student from Leuven) are really interested to join and perhaps even have a common position. I also got in touch with some authors' rights representative organisations, but there are a lot of them in Belgium, so it's hard to map them yet.
I am thinking now how to pool people's brain power. Mailing list, wiki page and the like. I will set up a ad-hoc wiki page on the WMBE wiki tonight. For now I am sharing a document (personal) where I just throw in the positions of people, parties and groups I have reserached. My goal is to make it into a comprehensive doucment. I will also continue to track and write reports about meetingsa and going-ons here.
