Change word "moderator" to "facilitator"

[vintagerv]

I've searched and can't find this one, but it seems easy enough for someone who knows the ins and outs of vBulletin. I'm want my moderators to act more like facilitators to get discussion going, and less like referees who blow the whistle on people.

So I want to change the word "moderator" everywhere it appears to users to the word "facilitator." How would I do this?

Thanks,
Steve
