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 ?
