Scream,
Finally got around to try and delete the extra tables and got the following error:
mysql> mysql -u username databasename -p

-> DELETE FROM w3t_Groups WHERE G_Id > 4;

ERROR 1064: You have an error in your SQL syntax near 'mysql -u username databasename -p

DELETE FROM w3t_Groups WHERE G_Id > 4' at line 1
I of course changed the username and database to my username and database names.
I also have figured out how I got so many groups. Each time createtable.php is run, it creates a new set of tables. I had errors when running mine and after attempting to fix the errors, I would run createtable. Maybe there should be something added to createtable that comes up with an error message that says the tables have already been created so it won't happen again.
