I followed steps to install it and doesn't work. Nobody answered from the developers. It is a real problem trying to download this program then it just not fly.

Is there any other captcha solution for 1.0?

I give this an excellent for the added security it gives to your CB website. The back end settings are well noted but I do have a suggestion. There is no refresh button that I can see that could be placed next to the captcha image - this would be in case someone could not understand the captcha image. Is this a consideration from the developer? Otherwise I deem this extension a must have for any CB website owner.

Our site has been using this plugin for several months and it is nearly eliminated spambot registrations. "Nearly" because a very rare few spammers do sit there and manually register, but CAPTCHA is the cat's meow for keeping the vast majority away. Please note that the version in the free downloads, according to our experience, requires Legacy Mode; there is an update for CB Documentation Subscribers (recommended) that runs in full Native Mode. As an alternative, the CB ReCaptcha plugin also in the JED is less customizable and requires registration for public/private keys (free at this time), but is Native Mode compatible.

Excellent plugin however users should note that you now have to subscribe to Joomlapolis to download the plugin.

Before I installed this plugin for CB, I spent 15 minutes every morning blocking spambot IP addresses from accessing my Web site.

No More SpamBots!!! yay! Now I can focus on defending against hackers and real human spammers and not waste time on the cumbersome SpamBots.

A great plugin for CB, but I can't manage to make it work in Joomla 1.5 Native mode (seems to work only in Legacy). I hope joomlapolis won't withdraw the development of this plugin!

I'm using CB 1.1 and Joomla 1.0.13. The plugin installed without any problems on the first try. I also like the feature that lets you pick the look of the font in the captcha.

This is a great extension. Simple to install - no complications at all. I used to get several automated registrations per day - none now. It should be considered an essential security item for anyone running CB!!

Initially the plug-in didn't worked on my Joomla 1.0.11.
I upgraded to Joomla 1.0.12 and by the help of Nant, it WORKED !!!

10000 of thanks to Nant for his personal touch.

The plug-in is so beautifully build, that using some small mods (available at JoomlaPolis forum) this captcha system can be used in anywhere within Joomla.

This is a first for me: not being able to get a CB plugin to work. I have been anxiously awaiting this plugin and reading the other posts, it seemed to be what I was waiting for.

Unfortunately, I have downloaded and installed, and I have no image (just a space for an image). Although other reviews state it worked for them "out of the box," I've so far opened two boxes and it doesn't feel much like Christmas. That being said, I'm sure it is something I'm doing incorrect -- the CB Team are incredible!!
