What are the new features? All I can see is that thread view has been removed - a loss of a feature. Being mobile accessible is, of course, good (but I don't use that). You said there is no limit on thread history but when I searched for one of my old posts, the search engine did not find any of my posts. I guess the cut over got rid of the history.
I'm going to check on the old thread history, it could be that perhaps that it's for all posts from now (the switchover) until "the end of time", I suppose.
Just a few of the new features are right here:
1. They are a
responsive design; meaning, they were designed for desktop, tablets and mobile - all in one design and all at the same URL. No need to go to a different address to get the proper version for your device
2. They have a modern, secure and actively maintained framework built for speed & stability
3. There will be
no limit on Thread History, so you can reference old topics or replies at any time
4. There is Private Messaging, Social Profiles and Rich(er) Content - embeddable video, embeddable Tweets, etc
5. You now can set up
alerts and
follow users so you don't miss replies to topics you're participating in or miss great posts from your favorite users. In your
News Feed you'll be able to see all of the topics, users, and content that you wish to follow.
6.
Dynamic quoting system so what you select within a thread can be quoted without copying and pasting any code. You select what you want to quote and click Reply over that selection, and it will be put automatically in your reply. You can quote
multiple posts and
automatic quoting is set up so that you can always follow the conversation with a user forgetting to quote.
7. Improved
navigation and
search: quickly jump to the first unread post in a thread or to the top and bottom of each thread. Advanced search features include by keyword, date or thread title.
