A few months ago, one of our local list owners asked me to create a special super-list. He told me to create three lists (list1, list2, list3) with the following configuration: list1: sub-lists= list2,list3 list2: sub-lists= list1,list3 list3: sub-lists= list1,list2 You can see, that every list is both a sub-list and a super-list of the other two lists. I thought that this would create some kind of loop and I was really astonished to see that it worked (on a 1.8d LISTSERV). Kind regards, Siegfried
