Number of posts per thread by username

Not long ago somebody posted a way to easily find a breakdown of number of posts per thread by individual members. (As opposed to going through a thread and manually counting.)

I remember doing that and seeing a breakdown something like this:
Poster A: 10 posts
poster B: 5 posts

like that.

How do you do that?
Or did I just dream the whole thing?

On the Forum View screen, click on the Number of Replies.

Ahhh! Thank you Achernar, I knew it was something simple.
