Oracle just announced that the planned update of the OTN forums to a new modern version has been posponed to June 2013.
UPDATE – launch delayed for four weeks, into June.
In a last minute decision we have delayed launch so that we can establish thread level redirects across the site. I am very happy with this outcome and expect a much smoother transition when we do make the switch.
Good move! Better wait until all links can be migrated than update and many links are broken.
