Haven't seen a single message, nor got a reply.

That said, I have only spent a couple of days messing with it so far.

It's possible that there is a community on a channel other than the default long-fast. But I haven't experimented with that yet either.

From my house (south perimeter area) I have only seen one other node. I have to do closer to downtown to see many more and that's still on the to-do list.
