I don't know what the procedures are for becoming an official trainer these days, but maybe it'd help if there was something like a "Trainer Associate" program. Some way to flag veteran players willing to drop in once in a while as trainers, but not with God Privs, so the newbies in there knew that the resources were around.
If this tagging was carried over into the MA, that may also get some newbies asking vets for help. Note that if the flag carried over to the MA, the player should have the option to cloak it. Otherwise flying AH becomes work all the time for someone who has volunteered to help.
