[MOD] Stop review spam disabling captcha
Posted: Thu Jul 01, 2010 4:58 pm
I've noticed a high incidence of customers trying to contact me using the Contact form but the Captcha system is so poor that many don't find it easy to read and I lose out on sales. Unfortunately the Captcha setting also determines whether you use it for reviews which I DO want to have because the spam bots are constantly hitting that function.
So, quick and dirty "fix" to enable Captcha for reviews but disable for everything else.
