Mentors - What is expected really?

[Freyt]

Heavy is the head that wears the crown.
But not really, a lot of them are empty.

Most of 'em just have it because it's a crown next to their name. Sad thing is I haven't really seen that many of them that wear it and actually act as SE had intended their concept of Mentors to be.
I had it for a while and eventually just went back to the Smith dude and removed the mentorship thing because it had no meaning.

You really can just change your status off of the mentor icon. That's all that is, like /busy or /afk. No one will be able to know you're a mentor without the status.
