For the "update article" task type, there are two different links used in the tips. In tip #5, there is a link label "add a reference" that should go to a help page about adding a reference. In tip #6, there is a link label "Learn more..." that should go to a help page about updating articles. Right now, they both go to the same help page about updating articles.
Also, we should make sure that if a wiki does not have a page about references, there should not be a link at all in tip #5. If a wiki does not have a page about adding links, the "Learn more..." text should not even be present in tip #6.
