I just want to bring attention to our latest feature at PF. We now have a "Top Threads" filter tab at the top of each forum. If you click the title text you'll have a quick filter that shows only threads that meet conditions we set. At the moment it only shows threads created by Homework Helpers, Science Advisors, Mentors, Staff Emeritus, threads with >30 replies, >2000 views and featured threads. If you click the drop down arrow you will be able to set your own conditions. This is a great way to discover content which you may have missed that is most likely quality and interesting. Also to note that we moved the "Thread Display options" tab from the bottom to the top. This will help sort results. Enjoy!
