Since v3 we also have a new wall. But I don't like the 'auto-messages' cluttering the place. Any serious discussion is just crowded out by all these messages saying 'x commented on y', 'z likes q', etc.
So I'm suggesting a little tick box where you can say whether you would like to see these auto-messages or not. That way we might be able to have sensible discussions on crop circles and the end of the world as predicted by ancient civilizations once more.
