OK then I am about to make the change.

Because the old forum name is embedded in each and every posting in old thread changing it is not looking like an option. So be aware you are not going to be able to reply to old threads. But new messages will work fine. If there is an old thread you urgently want to continue discussing you will simply have to open a new thread with the same topic name.

We have to change at some point ... and that is now.
