Help Unsubscribing to Groups

When certain activities have happened I have subscribed to several groups so I didn't miss new posts on them and could get to them easier which was good.

However, now some of them have become inactive and I wish to unsubscribe to them as they take up a lot of space, they don't disappear like subscribed threads when there are no new posts. My problem is I can't find a way to unsubscribe to them anywhere. I'm probably being blind and it's dead obvious but I don't know how.

Help?

 

You just need to go to the Group(s)
Hit the "Group Tools" menu (located on the right of the toolbar with the Group's Name, I believe. tl;dr it has a gear next to it

At the bottom of that, there should be an option to Unsubscribe. c:

 

Ah, that works, thanks!!
