To get any of those designations you have to participate in certain forums.
For example, the "fighter" tag is for those who have asked, and been approved, to participate in the debate forum. The "writer" tag is for those
who have submitted short stories and either won recognition or been awarded the title by virtue of active participation.
The scholar title? One I wouldn't have ( I don't think ) - if my mod title were to go away. So I am not sure of the qualifiers for that one. I think
it might have to do with the research forum.
