Hey there!
I am back with the same problem but on the next level. Thanks, @codinghorror, for showing how to edit the description of a category. We could do this, however, we could not change the meta description of a category. Every time, we run an SEO audit of the site, we get an error that the main community page, privacy policy page, ToS page, and category page have duplicated meta descriptions. So I am looking for ways to edit the meta description of privacy policy page, ToS page on our discourse account. Do you know of a way to do it?
