Are you talking about the theme? I don't believe it can be changed, since I don't see any theme changing options; I only see the 'change style' function under 'Preferences'
Erik, there's an option in WHM to change individual accounts' themes. However, I don't think we do this on a per-user basis, amrclutch1. If everybody else wanted the x2 theme, that's a different story, but I don't believe we change themes for individuals.
