Since free synchronous conferencing or webcast tools are typically harder to
find and scheduling can be an issue, these live events can work well to launch
or follow up on asynchronous discussions. For example, you could have a
real-time session to get acquainted, introduce key concepts and answer
questions. Use asynchronous tools for ongoing discussions or large or small group
work. Or start with asynchronous team projects and use the synchronous meeting
for reporting.
Chat tools are freely available and can be easily used to organize or plan team
assignments, or for small group discussions.
