Forum Vistas are cosmetic items that give your avatar an illustrative background while posting on the Flight Rising forums.
If you have applied more than one forum vista to your account, you may switch which forum vista is active by visiting your Account Settings page.
Under the Forum Vista section of your Account Settings page, click the Change button. This will open up a preview window displaying what forum vista you currently have applied, and allow you to change it by choosing another forum vista from a drop-down menu.
After changing your forum vista, it will remain until you change it again.
