"Eureka", but why?

Yeah, the more specific you are in your messages the more likely you will get the type of group you're looking for. Not always, but higher probability.

Agreed; train parties will take folks of ANY level, so long as they have enough high-levels in the party to get credit for the kill. I've seen folks as low as level 1 in my parties. If you want a low level mob-grinding party, you'll definitely have to be specific; a simple LFG will land you in a train party almost every time, regardless of the level you post.

Depends on the leader though. I try to get people 18+ when I'm leader just so that those that aren't 20 yet can still get EXP for the kills they help with, and so that we are more useful in helping to spawn the higher NMs(and killing/tanking the wraiths).
