Send fixed text in an e-mail using Form Builder [solved]

[Andor]

I'm working with the fantastic module Form Builder, but have stumbled on a challenge that I can't find a solution for:

I have a form that front end users will use to have their friends sign up, by sending an e-mail to them. In order for me to assist the user I want to add a pre-defined letter that is supposed to show up in the e-mail sent by the user.

What are my options? A field I missed, a new template or an other exciting option?

Thanks

Hmm, you can try to insert the text as a hidden field which is only shown in email template ...

Thank you, cyberman!

I managed to use a hidden field and include a user defined tag with the content of the letter.

However, in the process I also found the "right" solution: in the Advanced Settings for the form field "Email to User-Supplied Email Address" there is an e-mail template 

So, now I have a "Static text" field for the user to read his own letter before sending it and the above mentioned field to get the same content in the e-mail 

Thanks again!
