We're not turning Unity into a "real name" site. We're adding an option to display real names, that's it. Unity will accommodate Expertzzz users just fine.

As for Forumz - we'll make sure to save archives and move them to Unity forums.

Expertzzz is indeed a live site, but we're cutting down on separate projects, concentrating on just BoonEx/Dolphin, so we could spend more time for development and UNity management.
