On the main page of any group not only the members are listed, but there is a link "join this group". After you clicked on this link, there will appear the notification "You have joined this group" and your username / name will appear in the members' list.
Since all groups on openCards are generally open to all members, there are no restrictions to this. You may join any existing group and contact its members by writing them "private messages".
