The following Yahoo groups and other cyber-networks are forums to keep the CI world communities connected and informed. Announcements and information about classes, jams, and other events or news are shared here as well as other CI related questions and answers. Groups tend to be started to serve specific regions and/or topics of interest. Most of the CI related groups I've found are oriented around region. Some of these groups require that you become a member in order to post or view posts. The number of members (as of Feb. 2010) is listed in parenthesis beside each group. Low number of members either means that the group is newly formed, not well publicized, represents a sparsely populated area, or is a very specific topic. Our community is growing- as of February. 2010 over 12,000 people in total belong to the following groups!! The fastest growing groups seem to be Argentina, Boulder -Colorado, France, the Midwest (USA), Montreal, and Finland.
