If I get this right, all forum postings must be made to one group and there is no forum “outside” of the groups. That’s why I already created the “general” group. You may want to join that group first.

If you made a posting and forgot to select a group from the “Post In Group Forum” select-box directly above the “Post Topic” button, you can probably go back with your browser’s “back” button, still see the things you entered and can choose a group for your posting.
