Do you also hate to have all those spammers registering to your Joomla! site ?
Well, let’s put an end to that with the reCaptcha sollution.
This update of the Joomla! user register component will stop the fake users register into your Joomla! system.
See a Demo here.
The installation of this sollution is quite simple.
- Go to https://admin.recaptcha.net/accounts/login/
- Sign in or Sign Up
- Add a new site or choose your own site
- After creating the site or choosing your site you will be displayed a Public and a Private Key
- Unzip the Component sollution to a place on your harddisk
- Open “configkeys.php” in notepad text editor (the file is in the folder components/com_users
- Use the private / public keys from reCaptcha and add them on the place where the … ‘s are (so remove the … and past the codes into it)
- Upload the components folder (which contain all folders/files you need) into the root of your site.
- Done !
Please, do make a backup of your site before applying !

It appears that this document is not finished yet. I tried to install your plugin but it didn’t work. Does this come with a manual?
Disregard that last. When I posted the comment, it expanded the text. There’s a glitch that won’t let you expand text without posting a comment…
Brilliant! Many thanks!
Followed your instructions to the letter and we were up and running within seconds
Does this work with Joomla 1.0.x?
No, the files are hacked for Joomla! 1.5.x only.
If you want I can create a hack for Joomla! 1.0.x also.
