Okay guys, so I've searched online but I have not found anything.
Last year, I was able to go to my groups tab in my friends box and message all group members individually. The group tab looked like a the friend tab, but now it just says "View all members."
In my previous experience, only really large groups had the message that all of my groups now have. Neither of my groups are very large. ~30 members and 9 members is all they have.
Does everyone else's steam groups show up like this now?
Here is a picture so people can see what I'm talking about.
