Jézus Mária...!

I find step by step to add friend to public group.(ex: ABC)
Step 1: UserA create public group.
Step 2: UserB enter group name "ABC" to search box. Result show "No results found!" (because it search user)
Step 3: UserB click "Search Groups" to show group "ABC".
Step 4: UserB click to Join group "ABC"
Step 5: UserA click accept UserB to group "ABC"

In member group page, i find error

Can not see the group set up by acquaintances, so they can not connect.

Can not see the group set up the ismerőseimnél, so they can not connect.

Nem látszik a létrehozott csoport az ismerőseimnél, így nem is tudnak csatlakozni.

Are you talking about OssnGroups? if so it didn't have add friend to this group like facebook have, user can join by clicking Join group button on group page.

... and open group not visibled... i deleted this add-on.

Good question...
