The whole site lacks the cleanliness of design and crispness of PT2.0. It's a great shame that all the forum content and user information has been ditched, for a much less capable and notably uglier system. Not even migrating logins was a bit rubbish.

I know content and community is what really matters, but a little bit of presentation goes a long way.
