Interesting... but when I play on a different computer, it thought remembered what I had unfogged from playing on the original computer. There has to be something server side that saves a character's information.
For instance, last night on my home computer, I added a chat tab to one of my characters. This morning, on my work computer, I brought up the character and the new tab was there. I was able to save it with /chatsave and load it to all my other characters.
