So you don't miss a single email in your inbox about the GalaxyAdmins call, I'm sending the second one. This one has the necessary call details info:

The meetup's online conference room will open 15 minutes before the meetup. The call will use Johns Hopkins' Adobe Connect server, which in turn uses Adobe Flash. You are encouraged to connect a few minutes early to work out any unexpected bumps.

Complete connection details, including screenshots of the process are available on the event page: https://new.galaxyproject.org/community/galaxy-admins/meetups/2017-02-16/
