I have joined the IBM internal group called BlueIQ. This group is committed to helping IBM personnel get better use from their tools and make their day-to-day working live easier. One of the tools that we use extensively is Sametime Unyte. Sametime Unyte is a SAAS which allows uses to web conference and audio conference. Within IBM using this service is free (as you might expect) but it is really a service that anyone can use. Check out this cool video on this service.
