I'm with Art.

A suggestion.
I'm on another forum as well, which takes IP addresses and encodes them (only the administrators have password access to decode them, revealing the IP) but the encoded IP is always consistent with that, of the poster and is always displayed beside their "name".

If the programming wizards here at Mudcat, could come up with similar technology perhaps on a trial basis, I think this would discourage flamers and trolls. My gut feeling is that those who are currently smearing cyber "graffiti" on the walls of this "house", ARE members. Be a piece of cake to match up the encoded IP of a GUEST with the corresponding encoded IP of the Member. It would save the Mudcat "profilers" a lot of time. And then like I've advocated in the past, one private warning to the individual(s) responsible, and if it persists, out them or simply deny them access to the Forum by blocking their IP.

Just a suggestion.
