Registration check case sensitive - how to change?

[Coleen_Astalos]

We modified my validate registration form macro to check to see if the person registering was in the "members" group.  It appears that this check is case sensitive and I'm having a problem with that as members don't remember when they subscribed to my service whether they had any uppercase letters in their email address.  

This is how the macro checks membership - is there a way to change it so it's not case sensitive?

<n.users_in_group. group="Members">  
        <n.set_var. name="in_members">  
            <n.loop.>              
                <n.if.equal value1="[n.email_field.value/]" value2="[n.current_user.user_email/]">  
                    <then>true<n.break/></then>  
                </n.if.equal>              
            </n.loop.>  
        </n.set_var.>  
        <n.if.is_empty.remove_spaces.var name="in_members">  
            <then.throw_template_exception name="user_is_not_member" />  
        </n.if.is_empty.remove_spaces.var>  
    </n.users_in_group.>  

Thanks,

Please, try to use "to_lower_case":

<n.if.equal value1="[n.to_lower_case.email_field.value/]" value2="[n.to_lower_case.current_user.user_email/]">

That works.
Thanks,
