reCaptcha not working

[eluser]ponto[/eluser]
Has anyone gotten the reCaptcha to work. There is a link someware in the forum to a URL that are supposed to show reCaptcha i action...
That doesn´t work eighter. If you put in the first word and the first letter of the second it validates.
In case there is tutorial and working example pls. let me know

Thank´s

Thank´s for your reply PistolPete. Have tried this one.
I´ve been trying to implement the DX-Auth from a tutorial by Dexcell. Excellent tutorial.
The sad thing is that reCaptcha dont work and I haven´t found a working example anywere. I´m beginning to belive that reCaptcha has never been working and I am waisting my time.
