[Going Back And Adding Columns After Table Is Created]

I am in chptr. 9 Script 9.1 and have realized that i did not include the registration date in the users table when creating it, so the script wont run. I need to add the registration date column to the users table. What would be the easiest way to do it? would it be easier to just start all over?
