If my understanding is correct, at least part of the recent conflict between Anthere and Guillaume has to do with two people using the same nickname. I will take the opportunity to reiterate my plea to get rid of the nickname feature altogether.
The main reason is that nicknames make discussions harder to follow, especially if people keep changing them or use ones with undisplayable symbols.
Since the initial user name is already completely self-chosen, I can't see any justification for an additional nickname layer.
If I remember correctly, we initially implemented nicknames to accomodate users with offensive user names. This issue is now moot, since by consensus offensive user names are not allowed anymore.
