how to disable registration restrictions?

[countersweet]

note: i was directed to these forums by vbulletin staff, you can view the original thread here

how would i remove restriction that password must be different than username? and every other possible restriction too. i found some basic settings inside options -> user registration options but it only covers some basics like minimum name character, etc.

our user `registrations` are handled by another software (joomla and jfusion) which then calls registration function inside vbulletin, so i would like to remove every registration restriction that vbullet forces

what are they and where could i find them? i only encountered "username can't be same ass password" so far (and don't know how to disable it)

could someone help?
