When you use the SSO on the chapter website, a feature is available under the Events Calendar column called My Registrations. After signing into Member Login (SSO) in the upper right of the Home page, when you register for an event it gets recorded into the My Registrations list. This list is a great reminder of all the events for which you've recently registered.

The SSO also prepopulates the majority of the fields on the registration list; therefore this is just another great feature of this website.
