I had a look in at the webinar today (9/1/2014)
First you have to log in. Provide name, country (and state in U.S.A) email address and whether you have tested with ftDNA or another company. You then download the citrix software that allows you watch and listen to the webinar.
The webinar is a powerpoint presentation with the ability to ask questions as the speaker goes along. These may be answered in the webinar or at the end as appropriate.
The webinar’s can be quite long. Today’s was estimated at one hour but lasted one hour 35 minutes.
Presently there is no dedicated page for the webinars but they are working on it and it should come shortly. In the meantime the recorded webinars are on their facebook page. They did mention a site that has lots of webinars on genealogy and when I get the email they send to people who have listened to the webinar I should be able to post it. The new webpage when up will give details of future webinars
As all the webinars are being recorded and can be quite long I would recommend watching a recorded version so you can fast forward through it (assuming that option is available) but of course that will mean you cannot ask questions. They intend webinars to remain available for at least a month.
Finally thank you to DevonCruwys for giving the details of the webinars
