To get in on this discussion. I think Inzil is partly right that this messaging thing might benefit the committee more than the innocents, but I think the Seer would actually be the person most benefited if they get chosen (depending on when they get chosen). If they've dreamed of an innocent they could contact that person and let them know who they are, tell them the dreams, and have themselves an ally.
Really all anyone else could do is contact someone they feel good about. But only getting 1 message back and not being able to respond again makes the conversation very limited. And the committee would probably use this tool to mislead people in some way.
So I don't know, I can't really think right now how useful this will be, but hopefully it does end up being beneficial. But again, I agree with Inzil, I have no idea what it is most of us could really say, maybe something we're not sure we're prepared to suggest on the thread, so we could say it to one person to see if it makes sense? Even that though...
Anyway, this game should be interested. If people show up
