How to become one of them

[The chaser]

So, I was hanging out in this precious forum, and I asked myself "How do these guys with the purple names become what they are? The post count? The rep+? How are they assigned?

But, by looking at their profiles, I've seen it: The rep+ doesn't count (Apjjm has, now, less than me) the posts don't count too (Apjjm has 450, more or less)

So, are the moderators designed for the FG team itself? Is it an "election"?

I'm curious about them, so if some of them talked about what they exactly do, how, how they feel, how they became that, I would like to listen their story. As a secondary choice, you can post an image of your interface.

Cheers!
