I have been offering group seminars for many years using Webex whereby the participants sign in and can see my screen and we talk over the internet. The session is recorded so participants can play it back. These are 1.5 hours and cover major subjects such as the basics of cube handling, checker play, match play strategies, and many more. Groups range from 5 to 10 people max to allow for interaction and questions. Ideal for backgammon clubs, families, or any group of people interesting in advancing their game.
