If you use the Courier font it might help - then again it might not, but it may be worth a try. The reason for this is that the letters are all spaced at the same width. In this font the letters are only spaced as wide as they need to be, e.g. iiiii and mmmmm should end up being different widths on the thread, although they look the same in this reply box because it uses Courier font.

Joe Offer or another techno-head will probably give you a nifty technical solution using html, though. :-)
