Applying custom profile and registration fields

[Alkis]

Hello to all. This is my first post here. After searching on the hacks session, found some posts that help me better understand the code on vbulletin.

But I still have one question, that didn't found answered.

If you want to apply your custom fields in the edit profile, and registration forms of vbulletin, what files do you have to change. I am not talking about adding simple text custom fields through the admin panel.

I just need to know the files. Please answer ONLY if you are sure about how this is done.

Thanx in advance
