Hi, all. I thought I understood super-lists and sub-lists after reading the material, but now I'm not sure. I'm thinking of restructuring my list so that everyone subscribes to a super-list but only a few subscribe to the sub-list on a project by project basis. The sub-list would contain topics which don't exist in the super-list. Given this, who would received a message sent to the super-list if the message carries a topic which exists only in the sub-list? Another way of putting it: Can I create a sub-list such that a message addressed to the super-list but carrying a sub-list topic will be received by the sub-list topic subscribers? Jilla
