Hello Stew, it is not a stupid question. But if you want to join the Freifunk-Network - the easiest way to get all the information is to pop by at the weekly meeting of the Berlin free wireless community at the c-base (http://www.c-base.org). You can meet a great bunch of people there every Wednesday. It is Rungestraße 20 close to U8 + S Jannowitzbrücke. More infos in German at http://olsrexperiment.de and http://freifunk.net. See you there! Ciao Mario
