There is no link like that. It was lost somewhere along the line in some upgrade or tweak. Hopefully this will be available in the new software that is nearing it's live debut (I hope).
For now the best there is, is the
icon that appears after any 'new to you' topic in the board listings. And no, it is not clickable. See above for the reason.
Hope that helps. Sorry for any inconvenience or disappointment.
