Contact Form Populator...
Stack from Marathia
Version 1.2.0 released 6 months ago
This stack makes is possible to prepopulate text fields and text areas in the built in Contact Form Page based on a query string. That sounds more complicated than it is, and can be very handy when you want fields in a Contact Form to be filled in based on the link that brought a visitor to this page.
For example: you have a list of products, each with a link to a contact form where the visitor can ask for more information. With this stack it is possible to have the product name field automatically filled in in the contact form.
