Some time ago I created form_distribution, a TYPO3 template extension especially for different forms built with EXT:form. To keep this starter kit clear, I now outsourced the example forms formerly contained in a new dedicated extension which is available in GitHub, too.
This new extension contains examples how to use the SaveToDatabase finisher to save form values to the database (including FAL references to file uploads).
Today I added an example for a customized email template to use with the EmailToSender finisher. This also includes a personalized salutation in the email message.
I'll add more useful form examples from time to time. Feel free to send your own solutions as pull requests!
