Ahem...Sarah, what about AFK pushing...I mean AFK relocation? Not that I've been there much for that, but wouldn't that be a use for them?
Regarding Aaron's question though, I don't remember having to search them either. The only thing I can think of is they could be part of one of those side quests. I haven't really completed any except for skelly infestation, so I'm not sure. Just a thought.
