Than that is why lines are appearing. :< Oh well, at least the coding isn't wrong. :\ But other than increasing the line spacing, which would make the whole thing look awkward, there's not much I can do. :\
I'm uh, just wondering, are you using a browser other than Firefox? Because I see no blue line under PPC in my sig. :\ Or, it might be the theme you are using. I am using Johto Elite, which has no underlines. I just wanna make sure I have it coded correctly, :\ Thanks!
