here is a opinion from a noob:
Make a part in the forum where you can find the names of the mentors, where they are living and what they can learn. So you can find someone that can help you and that can meet you at game. Also if they have place to take care of a noob because if someone receve 50 noobs invitations that doesn't work.
Also before a game you can ask if they are some noobs and match them before the game so they can learn on the field too
