Our comprehensive alert system relies heavily on text messaging. In fact, we require all new participants to confirm that they can receive text messages in order to activate their account.
If you don't have a cell phone, but would still like to participate, you can consider creating a Google Voice account. Google Voice is a service that provides call forwarding, voicemail services, and text messaging. Plus, creating an account is free!
If and when texting is no longer a requirement, we'll be sure to announce it!
