I agree..gotomeeting or gotowebinar is the way to go..very small footprint, the software is java enabled so members can click on the emailed nightly link (done by the software) for the next day's webinar and watch and interact with the presenter..the presenter has full control over who to allow in and can dismiss as well..
I think Chartsky has much to share and is the REAL DEAL but, it is near impossible to follow and learn without the VISUAL part..
just my thoughts..
