One other thing, the forum’s primary language is English. We have users that speak German, Spanish, Portuguese and many other languages from all over the world, we cannot unfortunately cater to them all. So please post your questions and comments in English and use Google Translate if you cannot.
You probably wouldn’t want to enforce a minimum quality anyway.
There are still underdeveloped countries like Germany with horrible mobile Internet at ridiculous prices and those probably couldn’t handle the quality.
But I could see the server recommending a specific quality setting which is automatically set when creating a new channel, with the option to change it if the user desires.
