We have at long last opened the DBT forum back up at Mydbtlife.Lefora.com - just sign-up for a free user account and get started. You can either access this forum by accessing the "Join the Group" tab at the top of the website, or you can bookmark the forum to your browser.
Plus, as you read this post, I am actively working on embedding our chat room for group chats. I will post another announcement when it is finally in.
Thank you for the patience!
