Since you have a long string of characters without any breaks, this causes the name column to be extra wide on the individual topic pages.
Your current member name is miss_smartie_pants_yes_um.
All I am asking, is that you go to your profile (link at top right of message index page), and change your active name to miss smartie pants yes um (substitute blank spaces for the _'s). This change will allow the name to be displayed on two lines, and will help with the page layouts.
I don't think this request is at all unreasonable.
