We create a contact form through CMS Desk > Tools > Forms. The "Comments" field type is Text area.

For the notification email, we use a custom layout, with the fields as follows:

$$label:Comments$$
$$value:Comments$$

User inserts carriage returns (new-lines) in the text area and submits the form. When the email is sent through, it doesn't convert the carriage returns into html-suitable new-lines (e.g. <br/>), so all the text comes through as one paragraph. Either this should be done automatically, or we need a command to invoke this.
