not sure why you'd want to search on the 'wordpress extent page' , I don't even know what that is.
if you gave up after half an hour it shows two things:
- you clearly looked in the wrong area
- you're not very persistent
I usually recommend users with your profile (no offense here) to get in touch with web developers, that how they make their living.
But you could also starting getting acquainted with the principles of Wordpress and how plugins typically operate that allow to include data in a post/page (via TinyMCE). Or the easiest: read the help page that comes with cforms.
