I finally found how to mute "Projects in Copr" on
discussion.fedoraprojects.org.
It is now muted for new users and all **existing** users as well.
This should suppress this category from Latest and RSS as many people requested.
If you want to follow this category or topic in this category, please enable following in
WebUI once again. Your choice
will override the site defaults.
