Can I say "Knowing about something" or "Knowing of something"?
Which is correct? and why?
I found that the BBC also uses "knowing about" in this link: BBC World Service | Learning English | Ask about English, (There are two things worth knowing about the use of the pronoun 'whom'.)
There is still has a related question in this post,
I found that the BBC also uses "knowing about" in this link
In above sentence, is "uses" correct? I just add -s to use because I think that BBC should use third person singular, but I am not sure of it.
