Percy, what happened is that I jokingly changed Jons chat name...which he normally doesn't mind...but being a bit grumpy this day, he insisted that I change it back....which I was unable to do.
apparently, when the chat administrator first changes any given name, they can use the /fnick name any other name feature and the change will pick up the spaces. In changing the name back, however, we are unable to say /fnick (any other name) (next name) because the system only picks up the word, "any" (first word of name) and then tells us that "any" is not logged in.
When Jon gets testy with me, he insists that I act my age and chooses to nitpick at my position of responsibility. Perhaps I should act more professional so as to be an effective role model for our temperamental young Minnesota lad!
