i like to know how i can install automic emails when somebody put his order in the system, with a litle thank you, or with practical information about the seminar

Hi,

It should work by default.
If you don't get any email, it's probably that you didn't configure properly the "emails" settings of the Joomla configuration. So please check them with your hosting company recommendations.
