Hello,
I installed CB trying it before having membership ..
the problem is :
i want the username to be only numbers and 10 digits ..
so i did this :
in username field :
Field-specific Parameters
Minimum length: i put 10 and it worked
in Authorized input: put Custom Perl Regular Expression
and in Perl Regular Expression: i put /^[0-9]*$/
it kept accepting letters on registration !!! why ?
