Yesterday I spent about 3 hours assigning rooms for the people that will be attending Debconf5. It took me quite more than what I expected, but I'm happy with the results up to now
My main criteria is grouping people by country, because even though it's nice to be with people of all around the world during the conference, I guess that it's more comfortable to share the room with people that speak your same language. However, it's not the case for everyone, for example, there's a special room for the women of Debian-Women
I'll be publishing the first draft in the next days, if anyone has any special requests (like asking to be with someone, or asking not to be with someone), it's best if they send those requests to me now, before I finish this up.
