I mentioned this in the Chat thread, but it didn't get any traction. Would there be any interest in starting a Slack for the Filmspotting community? The board is great for a lot of things, but Slack has a lot of advantages and has worked well for other communities.
What is Slack?
Slack is similar to old-school chat rooms, but also borrows a lot from message boards. Messages are persisted, so if you leave and come back you can see what you missed. You can start threads within the chat and tangents can be discussed there. There are channels which are akin to the sub-boards here to silo different topics of discussion.
I think it would dove-tail nicely with the board.
