Groups can consist of radioboxes or checkboxes. Only one paragraph can be selected per group if radioboxes are selected while checkboxes allow the selection of multiple paragraphs.

The example above consists of three groups with two of the groups using radioboxes and one checkboxes. Here is what Mouser has to say about his program:

The Form Letter Machine is a program that will help you to write letters and emails by mixing and matching from pre-written paragraphs.

It’s useful for people who regularly need to send out emails which include different components in different circumstances. For example if you field technical support requests, or if you need to reply to various inquiries, etc.

It enables you to assemble text from multiple paragraphs, each one customized for a specific type of inquiry or response. You can build your own configurations using checkboxes and radioboxes and nested groups, and then easily write new letters or respond to inquiries by checking off the components you want to include. A real-time preview allows you to view the message as it is composed. The program also supports user defined variables, which allows you to quickly personalize the template with a name or other data that is specific to the task. The text is then copied to the clipboard and can be used in your e-mail program or word processor.

One interesting option is the use of variables in texts (for names and other parameters that might change). Variables can be easily defined in the interface and filled with values which appear instantly in the text.

Mouser has created a website for the program which is a repository for user generated form letters that can be used in the software program. The Form Letter Machine is available for download at the Donation Coder website.
