The Howto for adding a second hint is outdated.
You just create the new hint page with the appropriate name. So if there is already a hint, that page is something like:
http://wiki.ubc.ca/Science:Math_Exam_Resources/Courses/MATH102/December_2011/Question_4_(vi)/Hint_1
So you create a new page with the name:
http://wiki.ubc.ca/Science:Math_Exam_Resources/Courses/MATH102/December_2011/Question_4_(vi)/Hint_2
(for a second hint, and for a third, just do the obvious)
Let me know if that's clear enough and I'll update the page at some point too!
