A timer allows you to either time your Elluminate session or a participants presentation.
To start one simple click on the timer icon on your toolbar.
The next window allows you choose the desired amount of time in either a count-down or count-up view as well as to choose whether the timer is only visible to the moderator(s) or all the participants in the Elluminate session.
After clicking start to begin your timer, the timer window will appear that will let you either pause the timer or close it.
