FYI from the AATA.  I signed up for these alerts and received my first one recently.   See more below:

Interested in receiving AATA e-mail alerts?

E-mail alerts on bus service changes, service disruptions and other local transit information are now available from the Ann Arbor Transportation Authority (AATA) with its new service – MyRide.

Interested subscribers can receive e-mail alerts on bus route and schedule changes, detours, delays, press releases, board meeting notices and meeting minutes as soon as the information can be made available.

MyRide alerts are sent to subscribers on only the topics they choose. Subscriptions can be changed or cancelled at any time.

To sign up for MyRide, go to http://www.theride.org/EmailAlertSubscriptions.asp and complete the New Subscriber form, which asks for a primary e-mail address. A secondary e-mail address can be entered and there is an option to add password protection.

AATA wants to assure subscribers that TheRide will use e-mail addresses only to deliver the requested information and will never share e-mail addresses with anyone, for any reason.
