I just helped form the Pasadena ALumnae chapter and it is a lot of work. A lot of commitment and a lot of fun.
first step i would contact EO to see if they are interested in forming an alum chapter in your area. and then they will send you the needed material to get started.
Another good starting point is on the Website. the alumnae manual. I printed the entire book off ( when my family owened a mail box etc) so it was free to print, but these are the first steps you need to do first to get the ball rolling.
aoe,
Laura
