Can you consider adding a notification on the outside of the co-op building for invitations. I was invited to a group and didn't see the invite till a week later. I had already started a new group but if I would have seen the invite I would have joined that group.
Also I see there are no private messages for friends. I know there will be none in the future. Can we Atleast send a short message with an invite to the co-op or maybe a few fixed phrases to choose from?
