The AJAX sending/refreshing functionality is great and really well implemented... however under no circumstances does it process anonymous users. I know this is by design for CAPTCHA purposes, but if the anonymous role is granted 'skip captcha' permissions
(and so to all intents and purposes the Spread form looks the same as it does to logged-in users) it still doesn't allow for AJAX processing. Not sure if that's something that can be detected and dealt with accordingly, but would be great if it's possible. Would be a huge plus for me as the site I'm building will be dealing with mainly anonymous traffic.

Also, as an aside, a minor feature request - would be great that after the Spread form is processed (via AJAX or no) the 'Your friend's email' field clears itself, but leaves the 'Your name' and 'Your email' fields intact.

Also would love to be able to change the title/value of the 'Spread The Word' button.

Okay I'm done.
