[Thor Joachim Haga]

Yes, whenever there are new posts to a thread, the thread is automatically bumped to the top.

But if you mean a “new posts since the last time I visited” type of function, perhaps marked differently, or with a different colour or something, I’ll leave that up to Malte to explain. Not sure there is one. There is so little activity here, though, so fairly easy to get on top of things if you’ve been away for a while.
