The FWG forums are back, up and running on a new piece of software called Discourse! All of the posts and users have been moved over somewhat successfully. However, as a security measure in the import script, you will need to change your password to log in. If you have lost access to the email used for that, please contact @Makyo here, on email at firstname.lastname@example.org, twitter, or on the Slack.
Enjoy, and if you run into any troubles, feel free to drop a line in the forum feedback area!
