A formally implemented mentor system would indeed be hard to run, but I see no reason why eager rookie players shouldn't seek out such a relationship themselves. I'm not saying I can take every new OC under my wing, I don't have nearly enough free time, but I'm willing to connect. As has been said before, don't be afraid to come up and ask people on Lyssea's available RPer list if they fancy a spin, I'm sure I'm not the only one who would say yes when they're free.
