I've always thought the way avatar names and group names were placed to be rather silly. Why should first names appear on the same line as group names, leaving the last name all by its lonesome on the line below? This makes no sense and causes a lot of confusion with new players.
With SL's popularity increasing so rapidly, this really needs to be fixed. I don't know about you, but I'm tired of noobs calling me either by the first word of whatever group I have active or just by my last name. It would make a lot more sense and solve a lot of confusion if the only thing written on the top line were the group name and the ENTIRE individual name (first and last) were to appear on the second line.
