// So, I'm debating whether user_role should be defined as primary_user_role,
// and changed from maj_student to something like journal_host|journal_guest? 
// that would mess up though what links are displayed in the navigation 
// though... but that's inconsequential. there are other ways of determining 
// how those would be selected/displayed. 
// my journals
	// if not a teacher, display this
// family/friends
	// get_users and filter by family/friend role
// teachers
	// get_users and filter by teacher role
// students
	// if get_user_meta( get_current_user_id(), 'maj_teacher_students', false )
// yup, I think that's what we'll do. Oh, how I enjoy refactoring...
//
// or, another option is once again to revisit primary_role being a small array 
// of things... is_teacher could just check primary_user_role and see if 
// maj_teacher is in it. that'd be simple enough... and won't break anything 
// I don't think
//
// another way we could go about this would be to have a user meta of 
// journal_owner, setting it to true or not. that'd be nice because then we 
// wouldn't have to query the blogs table or anything. it'd be simpler and more 
// nicely cached. and, to top it all off, we could have a filterable function 
// that checks what user roles can own a journal and return that. I think this 
// would combine well with having primary_role be an array of roles... just 
// need to add a function taht would modify the user's primary role on 
// invitation. lets change primary_user_role to user_roles while we're at it
