Unfortunately, the web page encoding for YaBB is structured in a way that makes it nearly impossible for me to tell which styles are actually being applied to the message text. A0;One thing I noticed though is that I'm not seeing any line-spacing attributes being specified anywhere, so I'm not sure Ahribar is correct regarding the line spacing (though no doubt it'll help with readability, even if it isn't the same line spacing as the old board).[/color][/size]
