I just purchased xenForo, I used SMF prior. While at SMF I hired a designer to create a custom posting template for me. Basically, the user info was aligned on the right while the content of the post was aligned to the left. The next reply would then alter and have the user info align to the left and the content align to the right. The 3rd post would go back to the user on the right and the content and the left, and so on and so fourth.
This is a custom mod I already purchased so I own the rights to it already. But it's designed for SMF. I need someone savvy enough to interpret the code and make it usable in xenForo instead.
I can provide you with the customized "display.template.php" file that was created for me, just keep in mind, it's for use on SMF and also keep in mind that I request you don't redistribute it.
If you happen to see this before Monday, September 3rd, 2012. You can view a live demo of the template here. If not, here's some pictures of what I'm talking about.

Notice how the user info and content fields both alternate on every post.
