hi peter
thanks for the reply,
i am working on dotlrn and created some students, and a another table,with the start date and end date, if want to block the students to access their pages after the expiration of the end date.
do i need to modify the user-login page which is under the acs-subsite/www/register/ in order to check the end date and doen't login them is this is the correct way of approach i want some guidance regarding this.
thank you
