Whats the difference between themeDisplay.getUser().getGroupId() and themeDisplay.getScopeGroupId()?
If I retrieve Layouts (pages) from it, would they have any different URL pattern like, /web-or-user/<user>/* or /web-or-user-or-group/<group>/*?
I mean am I right to say that every user has his own group or something?
As I understand it so far, it seems like User Foo has group UserFoo and group GroupFoo so you can retrieve pages personal to Foo or group of Foo ... Am I in the good way?
