EDIT: the migration is now complete. Welcome to the new Discourse forums!
I just wanted to announce that we are soon upgrading the forums to the Discourse software, so don’t freak out if the forums suddenly look very different. All the existing posts and links will still work, and your account will still be intact.
Discourse provides a more modern interface than phpbb, and is also accessible on mobile. It will hopefully also help us better manage incoming spam. It has become quite a popular system for discussion boards in recent years.
You will be able to log into your account using your existing phpbb password, but you can also choose to log in via a GitHub or Google account, provided that the e-mail address matches.
