I have to say, there's no one among the regs here that I'd warn Mav off. He's a big boy now and can cope with most stuff. I think there's things he could learn from just about all of you if he takes the time to do so. I know I've learned from most of you here at some time or other, so I don't see why Mav wouldn't.
Maybe there's a few things he could teach you lot too.
