User login/register flow questions

I am trying to really figure out Spark as we have a bunch of customizations to do.

One thing that has got me beat already is the flow after registering/logging in - in the first case, once logged in I am totally changing the way it asks you to join a "team", and in fact I want to remove that entirely - where currently it says "t looks like you're not part of any brand! You can create one in your settings."

So I can see the controller and route where it shows the template missing-team.blade, however for the life of me I cannot see where it does a lookup and finds that team setting missing, in order to display this message ?
