What tool for the webinar would you suggest?
Should we simply stick with skype, google hangouts, or do we need something else?
Pretty everyone has skype, and I had a call with 24 participants for SSEDAS recently which worked very well. Video needs very good bandwith, screenshare is not possible. People need to send contact requests and then need to be invited to the conversation.
Can google hangouts simply be joined from a public link? I think one has to agree on installing some Google components, and then it runs pretty smooth. No idea about how good it works on linux.
