Subscribers can have custom user titles using html. You can select the font, font color, and simple functions like italics and boldfacing.
Just let us know what you'd like or, even better, include the html for your custom user title, and one of us will take care of things from there.
Cheers, and thanks for subscribing!
P.S. Mods receive this, too, though no other benefits of subscribers. It's small recompense for the work they do, but hey, it's cool.
