At the NFN4Good TechClub meeting held on February 3rd, 2015, we featured speaker Sean McDonald.
Sean provided his Google Slides and a Google Spreadsheet for the attendees to follow-up on the presentation.
We also use Google+ Hangout-on-Air as a video conference and screen-sharing tool. Here is the recorded YouTube video:
