LCWO потребители с общи интереси могат да се обединяват в отделни потребителски групи.
Всеки може да създаде нова потребителска група и да покани свои приятели да се присъединят към нея. Групите могат да бъдат частни (затворени, само с покана) и публични (отворени, общодостъпни). Всяка потребителска група има своя собствена страница с форум и свой собствен вътрешен списък с постижения.
