My guess is they are not happy with the original forum for what ever reason and are willing to take a chance on loosing long standing formites.
I just this morning after installing my new copy of Home Studio had an issue with TTS-1. It would not launch in HS and Professional. I have seen a few threads about this,, but of course the search function doesn't work.
I had to use Google. So there's a big reason to change things, for sure the search function needs improving.
Then I pondered posting a question about why this is happening after 12 years of using trusty old TTS-1, but I wasn't sure I should try the new forum or put it here so I just sorted it out myself and left it at that.
But that brings up the big reason for this forum, I new I would have received an answer on short notice.
and when a bunch of people are having the same issue it gets noticed by all.
The big question will be how many "helpers" will be lost to the new forum.
