we are running 1.8b on VM/XA just had 'one of those' situations I set up a new list for a class 1. the knowledgeable students immediately subbed themselves 2. the grad assistant did an ADD for all students 3. the prof did an ADD for all students I would have expected the message 'name replaced' for each ADD for an existing sub, but subscribers ended up with 2, or even 3 entries for the same nodename - one for each variation in userid - same userid, just different typing - one all lowercase, one first character uppercase, one all uppercase. Is this working as designed or did we omit something ( "ignore case" ? ) somewhere in our installation / setup ? Is the fact that the ADD jobs and many of the SUBs came from a remote machine meaningful ? -mike
