Sort nodes by latest comments on it I am using D7. I want to sort the nodes by the comment post date on it.

Like 

Node a created on Jan 03
Node b Created on Jan 05

Normally i can sort it either asc or desc. 

What i want is a node with latest comment will be in top of my views.

I am looking for a views3 solution. 
Is it possible ?
"Last comment time" is sort.



Then use 'Sort descending'
