The current contact form is easy to be misused to send spam. It would be nice to have some form of captcha, for example Google's reCaptcha, to prevent this from happening.
Included in Sana 9.3. The protection will be expanded to the other forms Customer Registration, and Write a Review page.

Maybee this one should be changed from "Under development" to "Live/implemented" or whatever as this is now available in Sana :-)
