Admin CP Log IP Address In userchangelog
 

I had a custom system that would log email address changes for users so we could easily reset passwords and roll back emails for user accounts that had their account "hacked" (more like they used the same login/password other places or were phished). Was going to convert my system to just use the data within userchangelog, but noticed it's not logging IP address of the person that made the change.

Would be terribly nice to log the IP address so you can track down who the culprit if they are hijacking accounts.
