I have been on several business webinars in the past year.....Yes this is not a bad idea if it's in addition to a live meeting....

The webinars that i have been on all worked perfectly......While you can not see the live event you can see all the graphics that they want to post and you can also hear the voices of everyone attending...

Usually they have a host running the meeting and on the side of each persons screen there is a box where you can type in your questions.....Usually within a few seconds the questions can be read by the host............I have never had a glitch signing on , etc........

These webinars are easy to save for the company.....
