Answers to Exercises

Answer 1:	False. The reason why MySQL AB can offer commercial licenses is because the company owns the copyright to the MySQL source code.
Answer 2:	False. MySQL dual licensing also covers the MySQL client interfaces, such as the C client library, and client programs, such as mysqladmin.
Answer 3:	False. MySQL software can be used at no cost by anyone, provided they adhere to the restrictions imposed by the GNU General Public License (GPL).
Answer 4:	mysql@lists.mysql.com is the main list for general MySQL discussion. It's the right place to ask for help when you encounter general problems, such as installation problems. You should not contact the MySQL developers if you have an installation problem. However, if you have purchased commercial support from MySQL AB, a support person might get you in contact with a MySQL developer. docs@mysql.com is the public address of the MySQL documentation team. You should report your problem to that address only if you find that the MySQL documentation is unclear.
