I was thinking - for what purpose on profile page titles (Profile, User Info, Signature, Extra details) are linked to settings page? As I found in template it is show only if user is viewing own profile. All this titles are linked to ?action=profile;area=forumprofile.
IMO it's useless. There is link to settings page in sidebar or dropdown menu. Maybe there is some use for it that I can't see?
I didn't see this at the start, but somehow those headings became links to the same page, making the links to change into a "visited" state and changing the font colour.
Its nothing special, and sure its redundant, as its just a link to the area where you could modify the values.
