This thread discusses the Content article: Forum offline at Saturday 23rd February

Any hints as to the new features?

Most changes are "under the hood", e.g. to remove the reload upon the first visit to the board after login and many things concerning security and the admin backend.
Other than that, there'll be a Quick Reply box, Forums containing posts and other forums and the possibility to save threads as "favourites".

The "Discussbot"-integration (discussion threads linked to content items such as this one) will be better and almost automated. Oh, and most imortantly, double posts will be drastically reduced if not eliminated.

Sounds good.

But ... why is the forum working today? Has it been postponed?

Postponed until evening - I'm busy with some other stuff at the moment, so there's no need to take the board offline at the moment.

Edit: done! Read on here.
