I had the following information from the readme file, but it didn't work:
1. Configure and enable the plugin in your LifeType control center
Template code - note this plugin will take care of checking if the
plugin is enabled or not, and won't show the form if
it is disabled for the blog.
NOTE: I have included the necessary template code for authimage and
hiddeninput by default. If you are using any other spam blocking
plugins that require custom template code, you'll need to add it to
plugins/contact/template/form.template (just like you need to do for
the "regular" comment forms). Let me know if there is code you need
to add, and I'll add it to the plugin by default.
