How do I meet online with non-ECU folks?

There is Skype but for a more secure and supported tool, Lync 

Lync adds sharing and collaboration tools so users can meet online, give a presentation, brainstorm using a whiteboard, share desktop/applicationsand more.

One of the most-requested Lync features is the ability to invite non-ECU participants to a meeting or presentation.

Available for both Mac and Windows from the ECU Download Center.**
