 get_or_create can be confusing to use because it doesn't pay attention to
 the object that is actually calling it. For example when calling
 {{{forumpost.participant_set.get_or_create(user=person)}}}

 it would make sense that get_or_create is referencing participant_set that
 is calling it and therefore would create a new entry to that result set if
 it doesn't exist. However, this is not the case. get_or_create merely uses
 participant_set to determine the type of object it is dealing with.
