Add More Than 1 Record At Once ?

I have a form on an asp page which is used to add additional users to
the DB, i.e. adding a UserID (PK on table), Password & Email.

The companies are allowed a max of 3 users. If the company only has
the default 1 user and wishes to add another 1 or 2, then the form
displays the current user details, not in text boxes as this is not an
adit data form. The additional user/s can be entered into 1/2 rows of
text boxes, user 2 & 3.

If they decide to add 2 new users, how do I add the additional 2
records to my db table on submit ? Code:
