My version is 2.0B4 to be exact. Invision and IPB software has a feature where you click "Quote" and that post is quoted and added to a que, if you will. You can click quote on as many posts as you want as you read the thread, and when you hit reply the quotes are all entered into the post form, in order.
This is very very handy when replying to a thread after missing out on it for a while. In SMF my users have to go through a whole process of copy and paste to quote multiple people, and they are used to the old style.
Thanks :)
