I'm of a mixed mind about this.
Yes, it would be nice to "teach RP" but in my opinion, newbs learn RP in a couple of days, and either adapt and learn from there or completely fly in the face of it, like **** and *****.
Yes, having 'classes' or even Q&A sessions would be a good idea, held in a Group tab perhaps...
Just remember that each player is in control of their character, if they want to be a typical Warrior/Merchant/Mage and max stats and learn skills and grind, they shouldn't be discouraged, as I know Donari has a personal dislike for anything of the sort.
So BASICS should be taught, but not "do things this way, our opinion of mechanics is this, you do/don't have to do that"...
Mostly focus on where IC/OOC is appropriate and go for gold.
Oh, wait, with Donari banned... who will run the school?
