How to add group members in Outlook.com using Google Chrome.

I go to outlook-people- I tried picking a person and don't see a place to add them to a group. I go to my group and don't see a place to add them there. It just adds them to my contact list where they already exist. I hate updates that make things "work better" 

Original title: My son updated my computer to google crome because it was going to be nicer for me. Now I don't know how to add someone to a group in my outlook  hotmail.  Any suggestions would be appreciated.
