Hello, Zen Cart forum readers!!

I wanted to know about adding new sources to my selection of options available to users.

I wondered if I should just re-run the install_referrals.sql file, with a simple addition: (line 9)

Code:
INSERT INTO sources VALUES (1, 'Google');
INSERT INTO sources VALUES (2, 'Yahoo!');
INSERT INTO sources VALUES (3, 'AOL');
INSERT INTO sources VALUES (4, 'MSN');
INSERT INTO sources VALUES (5, 'ZenCart');
Can I simply continue adding new sources in this manner, incrementing the number with each?

I am only learning PHP and mysql stuff TODAY, so I am VERY new to it! But it seems the SQL is safe in that it erases the tables it creates, if theyalready exist.

I know, using the tools on the mySql database is probably a better way, right?

just wondering.....
