See what groups my friends have joined on facebook?

[K]

I remember there used to be a catagory called "groups" under Info tab on facebook, and when i click that on my friends pages I can see what groups they have joined.

But can't seem to find this option no more?
I meant I want to see groups a particular friend is in, and in the old fashioned way from her profile - clicking the Info tab (that's where the "groups" catagory was, and it used to display all the groups she was under)
