Hi, i have a phpbb3 forum - at the moment it’s just a developer’s forum, but with the completion of my website nearing, i plan to set it up to be a normal forum, but already i am getting 2 or 3 spam memberships a day. I don’t want to have to accept all the memberships myself (it’s effort and annoying as hell for the people joining), and it’s already set to activation email, so i was wondering if anyone had any suggestions and links to particularly good CAPTCHA’s, at the moment it’s just using the standard words in an image CAPTCHA
