I have JetPack's Contact Form (Grunion Contact Forms) running with this plugin active: http://wordpress.org/extend/plugins/grunion-ajax/ and it works great. :) -- that's just FYI for anyone else looking to turn this to AJAX. Has nothing to do with the questions below though...
But I was curious if it was possible to edit the output message (screen shot here: http://ScrnSht.com/tygvyh )
I'd like to add this:
-text that says something like "we'll be in touch within 48 hours"
-maybe a link that says "now go read our blog" (and links to the blog page)
Does Contact Forms have CAPTCHA available without hacking the plugin, like they did here: http://wordpress.org/support/topic/captcha-needed-for-grunion-contact-form?replies=14
Thank you very much.
