For those of you who used legacy Slime2 widgets (run from a local HTML file), Socks has provided an alternative authentication method that should get them back up and running while my authentication service is down. The instructions are in the GitHub Gist below (click on the link in the embed).
If you previously used the "SEChat to slime2 Converter", congratulations, I have a solution for the Slime2 service being down and not available, introducing THIS FIX. The fix is also available for the converter as well, and can be used during conversion: socksthewolf.github.io/SEChatToSlime/
