A forum I was on before had a similar thing, and it was actually called The Adoption Centre. I got taken on really early, and it does actually help a bunch for someone that doesn't know shit about forum etiquette or how to not seem like you're a deranged 12 year old. 
I think this is something that could be quite useful, but Mahz is right, it'd be a hard system to incorporate without seeming too childish. That, and I mean, isn't this what the intro forum should be used for? People come into the intro threads and offer to answer any questions, but people never really seem to ask from there. 

That and I remember I was in a family feud once on a forum. That was some sick shit right there, I'll tell you hwat.
