For myself, the features that come to mind are
1 - the 5 different styles . Read this thread that has 5 style screenshots . Out of the 5 styles there is probably at least 1 for everybody. I would recommend everyone read this thread with the screenshots of the 5 styles. After that they can choose their favorite.
2 - if you copy a link from twitter/youtube that the software will expand it without any fancy embedding code, Here is a thread to check out that discusses embedding video. aka copying the link
3 - So we don't support a pure facebook 'like' feature but we have 'Thank you' which we use whenever we like a post or want to thank someone. To use this feature click on the thumbs up icon that is just to the left of the poster's avatar
What is some feature here on the new board that you like ?
