User blog comment:BertH/New Forums now available in Labs/@comment-70.24.250.110-20121201012832/@comment-10370-20121202004844

When you turn on the new Forum, it automatically archives the old Forum namespace pages -- which is really just adding a header at the top of those pages saying "Visit the new Forum". We're not archiving any of the other communication features with this release, because we want to see how people use it before we make any more changes.

We decided to archive the old Forum namespace now, because it would be really confusing to have two different features, both called Forum.
