Following up on the post by IWC Schaffhausen below, the latest I've heard is that:
The current website will go down today, and be replaced by an interim website today
As part of the transition, this forum also will go down today but not relaunch as a new forum until Monday.
Dates may change -there can be deferrals or accelerations of this schedule. It's a major task, but I think you'll be thrilled with the new forum.
Check in regularly. The best way, by the way, to go "cold turkey" is to buy a new IWC ,)
Wish us luck,
Michael
