You need a server-side database with the user names and passwords stored in it. Also server-side scripts to collect and compare entered data with that in the database. Which programming languages & databases are you planning to use for this?
database? i cannot reach the username-password database of the school, i just need users input username, maybe it logs in in the school page and controls, and sends the required info back to my site, and continues to registration,
meanwhile i am using dreamweaver, and visual basic for programming
