Customizing MySites

First, let’s start with how NOT to customize My Sites. As with SPS 2003, some people might think “Hey, I can modify things pretty quickly if I just go to the file system and change the template for My Sites there.” This is absolutely the wrong approach, and it will leave your site in an unsupported state. This means modifying any of the .aspx pages or onet.xml or any of the other out of the box templates files is off limits.
