I am currently
writing/trying to write a CAPTCHA plugin for Geeklog. The plugin forces anonymous users to identify a secret code (e.g., "294821") embedded in an image, so to stop bots spamming comments on a Geeklog site (
sample image). The only additional system requirement for this feature is GD support for the PHP installation.
I already have the code together to randomly generate such an challenge/response image, and the code to verify the user's answer, but do not currently know how I could glue this into Geeklog.
Then I found this thread. If you want to, I can help (with limited programming skills ) to integrate such a feature into your existing plugin - if you want to, of course. I see no reason to have another plugin if its only one anti-spam feature which could possibly be integrated into your well-working existing one. I don't care about credits or such things, I only want powerful anti-spam functionalities for my website!
