A timely advertisement just hit my inbox: an invite to a free webinar about running successful synchronous events. http://www.elearningguild.com/surveys/index.cfm?sid=283
These eLearning Guild webinars sometimes provide good insights and ideas and sometimes are less instructive. In either case, this one is free and you usually get access to the recorded session afterwards (just in case that time zone difference is a no-go for attending the live event).
