P.S. One extra option is that you could also add this info to the faction pages themselves, because a person looking to fix their faction may go to those pages to see how to do so, and a note on them saying "try Wolf form" could be helpful.
As is often the case, there are multiple ways people might go looking for this info, so my general advice would be to choose one place that you feel is the "correct" one, and then make other places link to it. How many others (eg. do you do the faction pages and the spell pages and the general "here's how faction works" pages like Faction Tricks)?
That just depends on how much time/energy you have
