Pardon the ignorance but by what means do most members post video to this website? I used the search function without success. I get the impression that most link to an account they have with YouTube. Do you need to share personal info with the provider in order to establish an account? Thanks for any help in this regard.

Use the icon 2 nd from the right on mouseover it says insert video.Insert the link from the video that you find by clicking on share. It looks like this.
