I don't think so, Luc.
Granted, I've been away from WWGHA since January and only noticed this 'Shelter' section today....
It's a good idea.
But the practical details need refining.
One, nobody wants to spend half-an-hour writing a reply only to have it deleted because it was the third reply rather than the second.
Two, even if one's reply is accepted, and the OP replies to it, one's subsequent response may be a few minutes too late, and so the conversation dies.
