Yes, the topic on the mailinglist about this forum has recently flared up again. No conclusions yet though. Whatever happens the main communications platform for OSM is, and will be for a long time, the mailing lists. Especially with regard to development subjects. Like it or not.

I do see the forum.openstreetmap.org pointing towards this forum rather soon though. If this forum is still hosted here or that it is moved somewhere else is of no concern to me, as long as the forum is easily accessible (e.g. through an easy to remember DNS name).
