The April 18 STC Chicago meeting was on Just-in-Time Documentation and Training with guest speakers Jacqueline Napier and David Orr. The PowerPoint slides can be found on the wiki that we created during the meeting (http://stcjitslides.wetpaint.com/) as an exercise in collaborative development.
Jacque and David will post new materials on the topic as they become available. Feel free to apply to be a Writer so that you can add comments and information. If you sign up to the wiki, you can also invite associates who might be interested in the topic.
