Hi folks!
If you can read this: Welcome to the same old forum on a new hosting solution!
We’ve just completed moving the forum from our own server to sponsored hosting by Discourse. A big thanks to Discourse! 
As part of this move we also changed our forum address from https://discuss.mopidy.com to https://discourse.mopidy.com and thus had to update all the Google/GitHub/Twitter/Facebook/Yahooo sign-on setups. Let me know if you experience any problems!
