which trigger is activatetion by mail in the register.php

[Vaupell]

if i set my board to have email activation, well i have.
great, now im running a mod that want to bypas email
activation if certain conditions are meet.

what triggers the email verification ?

i see alot of
if ($vbulletin->options['verifyemail'])

but what is its content, and how can i make it false so it
skibs those steps.

Thinking in the lines of

This is an exsample, and should not be considered useble code

PHP Code:

if ($vbulletin->GPC['yes_its_true'])
     {
// Do my stuff INCLUDING
// skipping email verification
// not sure what to place here, since i dont know the content of verifyemail
/// but something like    verifyemail = false
      }
      else
     {
// again not sure what to place here, since i dont know the content of verifyemail
// something like verify email = true
     } 


am i on the right track ?
