Or wriite it, mark everything ->ctrl+c, shorten it and post, then edit it and paste everything into the edit field. voila up to a quadrillion characters^^ (actually seems to be endless)

For the tutor roulette: no idea never used it before neither as mentor nor as mentee but why give them reward at all? I know enough people who really like to teach new guys as long as the new guys want to be teached. With all this rewards handed out left and right we only get these people we definitly don't want to be mentors as mentors....
