Yeah xD For example, Clown Manager and Forum Kaiser are custom forum titles. To be honest, aside from helping X10, I think the custom title option is one of the best things about being staff. Being a plain "x10 elder" was pretty boring after a while.
To become staff, watch for posts regarding any position that opens and how to apply. Otherwise, just keep helping out on x10, and you may just be picked to become staff.
There are also custom titles for the more creative staff members =D Like mine. Those are customizable for staff as long as they are not completely ridiculous (like no calling yourself "supersh!t")
