I'm on another site where once you click on a thread title in the menu that you have read before, you automatically get taken to the point you left it. Basically, it sets the Bookmark feature Mumsnet has already to activate on the last post that appeared on your screen. It saves time constantly having to use the bookmark button. A little bar pops up telling you that you read up to that point last time. It's jolly handy.
Any chance here?
