hook for password / email update

[zero-two]

Hi everyone.
I want an external db to be syncronized with the vb forum one.
i already managed to have the registration hook working so that every new user confirmed is actually backupped in my other db.
Now i want to keep this data syncronizedm especially the password and the salt fields.

i hooked an update script to profile_updatepassword_complete and the script is correctly called. but

PHP Code:

$userinfo['username'], $userinfo['userid'] 


are empty! where i can find the info i just updated so i can keep them syncronized?

thanks for your help!
