When you come on to the forum, while you are on the index page, at the right hand side there is a link 'view posts since last visit'. If you click on this every time you visit the forum it will list all the posts you haven't seen yet. All the new levels will be there, plus all the rubbish but you don't have to look at that if you don't want. This way you will never miss a new level again.
The only snag is that, once you have clicked it, you have to look at everything then, you can't log off and come back later or the pc will think you read them and they won't show up when you come back. This can take a long time, there has been as many as thirty posts sometimes when I look first thing in the morning.
It works for me, I never miss a new level.
