Hi, gang....
As others have said, the forum is just down temporarily while they change over to new software. From my understanding, they want the new forum to look and operate very nicely when it goes live, and that includes importing all of the member attachments over, and appropriately allocating them, before that happens.
Hopefully it will be back very soon......I miss it as much as everyone else (especially at times like this, when a new issue comes out.)
For what it's worth, I've had a chance to see the new beta forum, and it looks very nice!
If folks would like updates on the progress, they are periodically posted on www.scrollsawer.com, and there have also been several updates on the magazine's Facebook page.
