Hello MMiller, MFlorence, I would suggest to call the other contributors 'peers' rather than 'mentors'. In my view this would be a more balanced semantics in some wikis. Would you agree? Can this be made configurable on a per-wiki basis?

Aren't all users peers on wiki?
In the context of the Growth features, "Mentors" is a role. Like "Admins, "bureaucrats", "Patrollers"... are role at the different wikis.
Mentors are experienced wikimedians who volunteer to reply to newcomers' questions.
The term "Mentor" is translatable wiki per wiki.
