For as long as we run on vB2.x, staff members are unfortunately able to use HTML in their titles. Since titles are limited to 25 chars, the possiblities are rather limited, and if I see more than just bold or itallics, they will get a talking to. For normal members, you have an itallics title if it's auto-generated based on your post count, a bold itallics title if you have a auto-generated title for a high enough post count, and a normal title if you use a custom title.
