You can create a role with permissions associated with it, and then grant users that role. This way you don't have to repeatedly grant the same set of privileges to many users. THIS APPARENTLY ISN'T SUPPORTED IN MYSQL. Line 1 shows how to CREATE a ROLE, and line 3 shows how to GRANT that role to a user.
CREATE ROLE SalesClerk;
GRANT SalesClerk to mcmahonk;
