hello everyone,
i'm trying to build website where users/guests can send questions to the administration, after i created the fields i found that there's no option for submission in the menu.
can anyone help me with that !!!

Hi. You need to use the K2 user module. Once users sign in they will get the option to add an item. Of course this requires that you have set up the front-end editing properly in K2. Users should belong to a K2 group with the appropriate permissions.
