I made this for Grandue and he said that I could share it. I haven't had any bug reports from him after he told me that it works. It doesn't save truenames between Mudlet sessions, so you'll just have to check truenames when you log in or just never close Mudlet I guess.
I am retired and log into the forums maybe once every 2 months. It was a good 20 years, live your best lives, friends.
