New feature added

Ok, I am in trouble.

Barely nine days to our exams, and I spent over five hours today trying to get the 'read / unread' feature going. Try it for yourself ! You can mark some of my messages as read or unread, and they will be either hidden or shown accordingly. Saves a lot of screen space, don't you think ?? And you only see the posts you haven't yet seen !!

Play with it - and tell me if you see any problems. But I don't think I'll be able to fix it immediately ...

Best 'o luck !!
