In order to participate in an Invoke Pro session, you will need to download and install a Verisign certified browser plug-in, which enables your interaction for the duration of the session. No other component or software installation is performed.

The browser plug-in is a small component that works with your internet browser, and is active ONLY while you are participating in our session. However, if you wish to remove it at the end of the session, you can do so by following the instructions here.
