There's a site profile and a course profile. During usability testing, users couldn't tell the difference. There's no need to have separate pages for a user's site and course profiles. Much of the information is repeated.

• Change the terminology. Check how this structure is managed by meetup.com or others.
• Remove the link from the navigation block for the course (under Participants).
• Course specific information could be summarised on a separate tab or in an expandable section of a single course profile page.
