First time FOSDEM attendee, developer room manager. Two suggestions: I would encourage a voluntary name tag system. I saw some people doing that, and I really craved broader usage. It's really nice to be able to quickly scan some ones name and project information and perhaps make a connection you wouldn't otherwise make. I think trying to centralize registration and hand out name tags like at other conferences would be a huge PITA. But I would have been cheerful to hand make a name tag ahead of time. Perhaps I missed the encouragement to do so, but I would suggest encouraging that explicitly under the 'registration' section. Second, the address published on the web site does not work properly in Google maps. If you simply cut + paste the venue information, you get poor results. I had lunch with a gentleman who took the metro to the Erasme stop and lost several hours figuring out how to get to FOSDEM. If I look here: http://www.ulb.ac.be/campus/solbosch/solbosch.html (or on the English equivalent), the postal code is prefixed with a B- (so B-1050). Perhaps that's the problem; perhaps Google needs to be corrected. I thought I'd mention it regardless. With that said, I know how hard it is to always get complaints; studies show that one complaint can overshadow 10 or 15 compliments. I would be very sad if my email left an organizer with a net negative emotional boost. FOSDEM is amazing; it is an impressive and open and cheerful event. The originators and current organizers are truly amazing people who bring a marvel to the world each year. I would really appreciate it if you could construe that as at least 100 compliments <grin>.
