Completely disagree with you about the mentoring forum. While those who are older players may look at the old mentoring system with rose-colored glasses, it wasn't a complete success. The fact that it used a class slot is of course one drawback, but the other was the reliance on only players in your realm rather than throughout the island, meaning it could take a while for you to receive a reply.
I agree that we should have an IG system that encourages teaching the game, but that shouldn't replace the OOC mentoring forum. The wiki is outdated in so many areas that its usefulness as a guide is limited at best. Hardly anyone uses IRC, many people wouldn't want to even if they knew about it, and that's a completely OOG (and OOC) source, meaning you'd have to include that along with the OOC mentoring forum in things to get rid of based on your arguments.
Many players don't use the regular forum, and other characters IG requires you to be in a realm that actually has players who care enough to answer questions, something which unfortunately isn't always true.
I never said I would completely erase the mentoring forum. That ain't my opinion either. It will have its uses, like I said, faster reponses. So I'm not saying 'based on my arguments' to delete IRC either. I'm just not a fan of it. If I would have to make a decision, I wouldn't implement it. But hey, I'm not making the decisions, right?
