Having been "corrected" as to who could edit sub-lists, I was however puzzled because folks continued to get messages that it can only be done by the maintainer. What I finally realized is that the owner must own *ALL* of the sub-lists. In our situation, the owner was trying to add a list they owned. However, he did not own several of the existing sub-lists, and that prevented his changes. Note to Lsoft: could we have a better error message, like, "In order to edit the sub-lists parameter, you must own ALL of the sub-lists that are currently or will be included."
