Is there a map of my Katmai space that shows me where to find other users?

Oh yes, there is a map! To access it, open the drop down menu under Users and scroll to the person you're looking for. To the right of their name, you will see a 3-fold map icon. Click on it to bring up a map of your space. On it, you will see a glowing blue dot where that person is. You will also see yourself depicted as a purple dot for reference.
