Hi, I am working in both the USER_AFTER_UPDATE and PROFILE_USER_UPDATED hooks. I want to be able to trap when a user changes just their username, so I can update a username in another system, and I will also need the old value of the username so I can perform a lookup based on the old username. Does anyone know how to pull out what field got updated, and the previous value of the field? I see that is gets populated and sent in a system email, but I cannot seem to find out how to implement it in my site.php. Thanks in advance, Brian
