Change of profile

Hi

I wish to change the profile at punbb so i can ask peole to add their address, zip code, country, phone number, etc. and i have located several of the places in the profile.php i need to change, but i have not been able to find the spot where it is updating the profile if clicking the button on profile.php?section=personal&id=id

Can anyone tell me where the mysql update section is?

Sincerely

Mads Jensen
