OMG -- I'm still pretty new to MAC/Apple, and just today was the first time I've been to icloud.com. I've been trying to create a new group in my MAC Contacts. But when I went to icloud.com, Contacts, I had no problem creating a group with the name I wanted...and lo and behold, when I went back to Contacts on my MAC, there was the group.
THANK YOU very much...
