Screen sharing is a great tool to use during a webconference, but you need to clear the decks of open programs. They may slow down your computer unless you have a real muscle machine. Plus if you have other programs open, websites, or whatever displayed on your screen than the screen sharing function will pick it all up, show it to everyone. The consolation is they can all see the closing documents de-digitize and fade away–a great start to a webconference! Also prepare your desktop in advance. Have the documents ready to go. And be sure to check for stray documents on your desktop that may provide a window into your company that you would prefer private. So remember to Clear the Decks!
