You get to set how people enter a group when you make it (Public, Invite, Private), but I can't find a way to change it in my made group!
What I did:
1) I made a group on the "Invite" setting.
2) I looked in the group settings for a way to change the group entry to "Public," but I can't find one.
I'm using Chrome, but I don't think it matters that much. :P
If I'm being blind, please let me know! ^^
