XF 1.5 Spam in contact form

[triforceguy1]

Hello,

Recently I've been getting spam in the contact form which is getting quite annoying. From what I understand, changing the CAPTCHA to Question and Answers will help alleviate this issue, however this changes on a global scale, and I'd rather use reCAPTCHA for registrations.

Is there a way to allow reCAPTCHA for the contact form, or at the very least set reCAPTCHA for registration and Q/A for the contact form?

Thanks in advance
Leon
