How to use multiverse?

[Rob]

I am still new to the app and wanted to know what i can do in the Multiverse Map.
I can see others ( probably users of this app )
But can't click on their pins to either check for trades or to find players in your area...

Green pins you can click on and see their trades. Purple you can't. And all you get is usernames so you could use that to message through the forums.
