Just a comment about Michael K's suggestion of 25-Sep-00 about displaying IP addresses.

My place of business uses DHCP. That means that every time I log into my work computer I get a different IP address. IF I were to join Mudcat threads at work (I said "if", I didn't say I actually do such a thing), my Mudcat name would probably show a different IP address each time. If other 'catters noticed this, SOME (not all, of course) might assume that different people were sharing a name and comment unfavorably.
