I'm not agreeing with the whole idea of this thread or anything, but I just want to point out that I've SEEN shouts over and over in places like Saw Mill and Gold Beach asking for help with non-PS and non-SMEB/SMOB-related quests and everybody ******** ignores them.
Don't act like higher-level players are such saints who will help anybody out, no matter how n00bly. Sometimes it IS hard to find a crew for Old Aqueduct or Otami Ruins or Duneslam because everyone on the frickin' server is just on to do DMS or gold-farming instances.
Marshall's Little Helpers is always a viable option, though. And they DO help people for free.
