This sounds like an awesome thing!
BUT... Lots of ambiguity.
Seems to be many details left out that could, and should, be easily enough included in their respective areas (pay, housing situation onsite, etc).
Lovely, lovely idea but I guess without those details clearly stated in the ad, your response might not be as great as you'd like. Hope I'm wrong. I just know I think this idea rocks but it's not stated clearly enough to make me want to dive in.
Cheers!
