I'll use this thread to highlight some new features as I learn about them. The first is obvious - MOBILE FRIENDLY. I know this has been requested a lot. It is a responsive design that will work on your phone, tablet, computer, etc. If you are replying to a thread and someone else posts before you're finished, a little note will pop up letting you know there are new messages and it will allow you to view them without losing your reply. Likes - You can now "like" a post or thread by clicking the "Like" link at the bottom right. User Tagging - Type the @ symbol and username and you can select a user to tag. Feel free to add your own discoveries. I'll update this post as I have time.
