I've never even heard of the mentor system in action. I thought about becoming one until I realized how absolutely useless it is. It's a good idea, but not enough participate in it to make it worthwhile.

Even though I'm not a mentor, I answer a newbie's question if they ask me. It's polite. I try to give newbies good advice when I see them out in the field. In the past, it wasn't uncommon for me to buy a warrior his first great axe because he was using a sword--that was my biggest pet peeve for a long time.

One of the biggest reasons why I think the mentory system fails is, as was already mentioned, that the level requirement is only 30. There are a bunch of people at level 30 who are complete and total newbs. The highest job I've leveled is level 40 (I'm lazy, so sue me) and I ran into newbs consistantly through every level. Level 30 players still don't know much about the game unless they've really done their homework.
