I like to let Jim transfer all Webinars to Youtube so that everyone at any time at any place can view his presentation.

I like many Webinars presentations, but mostly I miss all interesting subjects, because it provides the presentation at a fixed time, and one cannot review it again later.

Hi Weng,

Not sure which webinars you signed up for but I nearly always get a link
to watch the webinar again. The last 3 where Doulos, Microchip and
DVclub and they all send me a link to watch it again.

I am not sure youtube is any better platform given the excessive adverts
I am getting lately (might be because I also click skip ads as quick as
possible.....)
