Note: During your Trial Period, you will have access to all features found in the Platinum license and have access to all client-side Extensions and Plugins. When your trial expires, if you have not upgraded to a paid-for license, the signature features will gracefully downgrade to the features found in the Free license. Free licenses are valid only for personal accounts.
