As is, I have to keep a list of characters I met in game and whose names my char really knows. That was one feature I liked about Illarion, the game kept local lists in your character profile of people you have met on that character, making everyone not on that list show up as anonymous. I have read the threads about using "introduce" feature, and people's general concern about how it would work for chat windows, but I never had a problem with chat windows, it's pretty easy to keep eyes on the screen and note who said what by the speech bubbles, because they hover around for a pretty long time, and since you could nickname people, you would see your assigned nicknames in chat window.

there is a buddy list. press 'B' and it will pop up. you can add/delete names off there. I usually add a name everytime I'm introduced to someone, also GM's names just incase I need to contact them.
