Gonna dive into problem with profile page + separate code into smaller includes to make more maintainable.

• Make file: sidebar_left.html
• Make file: sidebar_right.html
• Make file: center_content.html
• Fix bug
• Include above in profile.html

Great! Good luck!
While you are at it, please make sure class and ID (especially an issue here) multi-word names are seperated by a "-", per Yam and Google.
