Currently most of WirelessCommunities around the world are using mailing lists to organize themselves and work on projects. A few in the North West are also using wiki:WikiWikiWeb to work on collaborative documentation. Here is the list of all the wireless mailing lists and community mailing lists that I know of. You can find more specific information on the lists hosted by PersonalTelco on the MailingList page.
