The concept of divisions was implemented for the first time on October 13, 2002. Prior to this system, Expansion Fleet was divided in four sections: Starfleet, the Corporation, the Romulan Fleet and the Cardassian Fleet. With this reform into divisions, the Romulan and Cardassian Fleet became divisions of the Corporation section, and in November 2002 the Corporation Interpol Division also joined the Corporation. In August, 2003, Expansion Fleet and the Corporation parted ways, and in October 2003 Expansion Fleet started a new section called the "Delta Alliance".
Expansion Fleet contained in total more than 25 divisions, though they were not all active at once. Some joined, left, merged together and were closed down over a timeframe of about 4 years. On September 21, 2006, all divisions were put on hold except for Avalon Division and StarPhoenix Base. On November 1, 2006, the concept of Divisions was abolished altogether.
Below are the names and banners of various divisions, sorted by join date where possible.
Avalon Division
This was the main division of Expansion Fleet.
StarPhoenix Division
This was the secondary division of Expansion Fleet.
Shadowfleet
This division joined in November 2002. It closed down on March 1, 2005.
Another Shadow Fleet RPG appears to have been created at a later time (presumably in 2007), before Expansion Fleet came to its end, and appears to have become the place where several of the players moved to when Expansion Fleet closed down. As such, it can be considered to be a follow-up (though not necessarily in storyline). Their website is at http://www.shadowfleet.org/.
