When clicking their username, a user should be directed to their profile page. The profile page needs a link that says 'Edit Account' or 'Account Settings' that then links to the Account / Personal Details Section.
Also, a users news feed should appear as a tab in their profile alongside 'profile posts', 'recent activity', 'postings', and 'information'.
Both of these may already be possible, if so I would love to find out how to do this!!
