How to mute community from feed?

I have very narrow, well-defined interests across most areas of my life, including how I use Digg.

I’ve selected communities that align with those interests and remain open to discovering new ones, so I use both My Feed and the general feed. That said, I would strongly prefer the ability to completely exclude communities I know are of no interest to me.

A true “mute” or “hide” option would prevent irrelevant content from cluttering my feed and help higher-quality, relevant posts rise to the top.

Am I missing something, or is there currently no way to mute a community via the three-dot menu?

Thanks!
