It's undeniable that there aren't enough mentors, official or otherwise, spread throughout the game to teach everyone who wants to learn everything they want to learn. So in that sense, I think having information available for the people who can't get it otherwise is a good thing.
What I don't want this mentoring forum to become is a replacement for IC interaction. Not ever. I don't want to see "Welcome to RealmA, if you have any questions, check out this link." Ever. Ever ever ever. I don't want new players to study the forums for a week and then go through the motions of playing to get positions. I want them to actually play.
On a related note, there's a lot of talk about the problem of the new character/older player getting positions before the older character/new player. Have the older players considered not taking these positions when they're offered? If you think it has a negative impact on the game, then why accept the position at all?
