I noticed this a couple times too. All my emails that come from threads where the content has some type of code tags and such look that way too. I'm not sure if it is the forum, the email server sending them, something they use to post with, or a combination. Other vBulletin forums I use don't have the issues. I had reported something when I first started writing here too about the dropdown menus appearing off to the side. The only thing I can see just looking is other forums aren't restricted in width and centered like this one. Others usually take up the full page. If I shrink my browser width the menus appear better, but other issues are still there. Something is set different for how things are rendered.
