That makes it a lot easier to understand. I was confused on how messages propagated. Your last paragraph is what cleared it up for me. Won't this lead to strange comment chains? You could have a hundred different people commenting on a chain and they're all a mix of federated and Def federated instances. Some will see some comments and others will see other comments but none will see all the comments unless they're completely federated with all the sites. This is where it loses me. Not that I don't understand what's happening, it's I don't understand how it's supposed to work in a threaded environment. I guess once I start seeing in an action I'll get a better grasp of it. I don't think this is going to work out as well as it was intended to.

Cheers.
