I'm not making stuff up, take a look at this screen shot. While yours if you go over too many characters it looks crap, mine dynamically preserves the formatting, allowing you to go much higher. Hopefully this should explain what I mean... You've interpreted my warning message as an error, and not actually tried pasting into the nick.
BetterMSN was always going to incorporated BetterName in it, ever since Chrono first used a coloured nick which was really early in the testing program. Everyone borrows ideas off everyone, I'm going to borrow and enhance nick styles, but that came from DToX's originally.
