Create new group
First of all you need to go to group directory, simply click on the Group directory in the left hand menu panel.
From here you have to click on the action button which is located at the bottom right of the screen, which looks exactly the same as the following image:
Once clicked, a modal window will show up where you fill out name of the group, add members and select its visibility.
info_outline Note that even though you are creating the group, you don't have to be a member. So if you are setting up a group just for your colleagues and don't want to be a member, click the X next to your name in the member list.
After clicking on the Save button, the group is created and you are redirected to the group details (in case you are a member of the group, if not you will stay in the group directory).
