A lot of wordpress mu spammed by auto script. Spammer(sometime is seo people) use auto script to generate account and post the rubbish. I created a simple captcha (Completely Automated Public Turing test to tell Computers from Humans Apart) validating to avoid auto script sign-up blog's account. Hope this may protect your blog. See here to to integrate the feature.

Hi CEO. Thx for the captcha solution. These damn Spam Bots 
I had trouble cause my Version of GD does not support imagerotate().
The Problem is on line 58. I just replaced the line with this:
$rotated = $buffer2;
Yeah i know i am lazy, but it works for me. This weakenss the captcha, but its better than nothing.

Sorry to say but in the latest WPMU 1.2.1 it doesn't work. Please update.

Download and setup wp-valid-2007.zip "Please enter correct code" - I solved this by putting this line: session_start(); after function validate_user_signup() { $result = validate_user_form(); extract($result); in the wp-signup.php so that it looks like this: function validate_user_signup() { $result = validate_user_form(); extract($result); session_start(); AND I had to comment ("//") a session_start() at the beginning of wp-signup.php //end hack Now it works perfectly!

SinusCom + others having trouble with 'headers already sent' message. Turn on PHP output buffering by doing the following. 1) first line of wp-signup.php (after the line obviously), add the following: ob_start(); 2) follow gam's post instructions above.
