General questions concerning contacts and general use

Hi. I just got my account going. Currently on basic, but plan to upgrade to personal soon. I'm not understanding contacts. What I WANT to do is create a list of emails that my check in messages goes to. Is this contacts? If not, how do I create that list of emails? Are contacts separate from Emergency contacts? 

I assume that without tracks turned on there's no way to look at the map and tell where I am? Or will this still work, only showing where I'm currently at?

Any help or advice most appreciated.

  • Probably correct. Personally, I stay as far away from the Messenger app as possible except with the Messenger device. But yes, if you sacrificed your number to the Messenger app, you will not SEE messages from iR devices in your standard SMS app. So you can't reply from there. You will need to use Messenger...
