[omaha] February meeting 2014

[Steve Young]

Since Lea was the only one showing interest this month, and no one could
entice Joe to abandon CERT, let's wait until next month.

BUT to help make it happen - does anyone have topics to share (Wes?) or
want to talk about?  Lets build some enthusiasm!

Steve
