Description
Protect your forum from spam registrations by using Recaptcha.
Installation
Create a folder called “recaptcha” in your bb-plugins directory. Unzip all files into that directory.
You will need to sign up for a Recaptcha Account. You can do that at https://admin.recaptcha.net/recaptcha/createsite/.
On signing up, you will receive two keys, a public key and a private key.
In the bbpress admin, browse to Plugins > reCaptcha bbPress, and put in the public/private keys in there.
FAQ
I have an error even when insterted both keys.
For some reason, I find that you may need to put in a trailing space when inserting the public/private keys, check if it’s present.

Comment Rules: Very simple people: be nice, be friendly, be awesome. Any comment which will consist of "My Keywords I'm Targetting", or contain your URL in the comment text will be marked as spam. Pseudonyms, names and "Name/Pseudonym | My Site Name" are fine. Also, don't just thank me. Seriously. I get enough adulation from people. Thanks!

I tried the plug-in with bbpress 1.0.2.
Unfortunately, if I enter the two words (but mis-typed)
the test often succeeds anyway. Is there any kind of
debug log I can enable to see what is wrong?
Thanks,

The way in which reCAPTCHA works is by supplying you with a word that it knows what it is, and a word that it doesn’t (all the words are scanned from books). Therefore, if you get one word right (the word that it knows) then it will let you in. The security comes in the fact you have to put a space between them (something that bots have to code in), and the fact that the words have special characters in them sometimes make it tricky to break.
