I put on a PowerShell presentation this past Wednesday night for the Fredericton .NET User Group.
It was a blast! Using Live Meeting is a very cool way for me to extend the reach of giving out PowerShell presentations.
I would be willing to give such a presentation to any user group. Just send out a feeler email to your members if there's any interested, and let me know via a comment here (leave an email address) or email me at marcoDOTshaw_AT_gmailDOTcom.
I do all of my PowerShell virtual user group meetings via Live Meeting.
