Today is March 6, 2017 and we have (re)launched our forum.
The forum is running on the Flarum engine. It's an open source PHP and Mithril.js project with a growing community.
Flarum is still in its early days so maybe you will be missing some functionality. However it is really easy to write extensions for Flarum so just drop your requests/feedback here and I will try to make it happen.
Also just let us know what you think of it
