For now, we just have e-mails available, but we're planning on expanding into other forms of communication. When you create your message, you specify how often you want to check in. Every day, every 2 days, every week, every 3 weeks, etc.
Once your message is created, you just need to check in by logging into the site. If you don't check in, it's not a problem. We can confirm with you before sending out the message in case you don't check in.
Know your message will be sent.
In the event that something happens to you, your message will go where it needs to.
