Not sure how to set that up yet. If you log off the forum each time you leave the computer then the next time you log onto the forum it will show you all the new posts since the last time you logged on.
The Little TW picture to the left of the forums will change into a Yamaha symbol when there is a new post, then you enter that forum and there will be a little round dot next to each thread that is new since your last visit.
Hope this helps.
