Right now only boards, topics and user-pages are supported, and it's read-only, but over time I'd like this to become an increasingly-useful alternate interface to bitcointalk.org. (Only when it's feature-complete and bug-free would bitcointalk.org switch to Epochtalk.)
If I understand correctly that means that in future each member would be able to choose between current ''old'' forum theme, and new style we can see on demo.epochtalk.com?
PS
New style looks very clean, I just hope someone thinks about adding dark theme switch, in current state it is to bright white for me.
