Manual Install Instructions for SMF


NOTE: This mod is now unsupported. SMF 1.1 has a CAPTCHA as standard, and you may install the  Advanced Visual Verification mod by HarzeM to get a more advanced CAPTCHA system :)

This MOD enables CAPTCHA-based code verification for SMF. Basically, this means that when a guest tries to register or sign-up, they need to enter in a code displayed in an image. This prevents bots from signing up, and also prevents bots posting in topics (if you have guest posting enabled).
