Along with a chat feature available to members so they can discuss or fight in real time,there are going to be several hundred small improvements to the forum.
Overall they shouldn't change the "feel" much. Things like customizing your notification sound for instance, and assigning specific sounds for specific people.
Let's say Mainemann changes decides I'm an asshole "Which he has" he can change the sound when I comment to "The asshole has commented" or some such thing.
Other things like being able to moderate your own threads and kick People off the thread you don't like....lots of things I'm working on.
