Q: I joined a second (or 3rd or 4th) Guild and now I am no longer on the roster!

Users that belonging to more than one guild site must set their “associations” 

In “Character and settings” then “Character Tab” then “Character Overview” look for “Manage Guild Associations” towards the middle of the page click on that and set what sites you want to show up on the roster.
