Another new feature.
In your control panel, under "Options", you can chose to collapse the threads that you have already read... new posts will show up "full size", all the others will be one line, showing the author's name, a post subject (if any) and the date and time they posted.
The point?
Makes for less scrolling. you'll notice a + or - next to the author's name... you can click that to expand or contract individual posts. Also, at the top of each thread you can "expand all" or "contract" all.
Note: unless you chose this option in your control panel, expanding and contracting will not stick... meaning you contract them all, but when you go back to the post, it won't remember that you did it. :think
