Look for addon for user stream / message board in nc

Hey all,

I look for a solution / app to communicate async with member in a NC. I think about a public board or message stream like the twitter streams, facebook wall etc. I want a internal system without social media service xyz :slight_smile:

The next could be a notification as email, app notify etc.

I’ll thankful for some ideas or hints for a solution. Let me know what you’re think about it.
