The character management page has been updated so that you can declare if each of your characters is active or not. This is to clear up some clutter with listing characters while viewing threads, and will also be used in future tools to better assess how many active players there are per game at a given time.

Inactive characters will be removed from your character listings in threads, but all of your characters will still be viewable by others via your profile.
Currently all characters are active by default, so if you want to make one of your current characters inactive, go to the character management page to update the settings.
