Hi,
I should actually point out that you are advised NOT to use a captcha.
Contact us forms etc. are things the user will fill in willingly enough.. Back In Stock Notification forms aren't just a useful convenience for the customer, but a great marketing tool for your site.
A captcha is often a step too far for the customer to be bothered.. they'd have to really want the product to bother with a captcha.. entering their e-mail twice is more than enough bother for most people (people are lazy).
So my advice is don't shoot yourself in the foot applying a captcha for the sake of it. It wouldn't take long to add a captcha but you'd have to come up with a very good reason, and I can't see one, give what I've said above.
All the best..
Conor
