All is in the title, how can i make my captcha display sometimes (say 1 out of 10).
I do not realy like constraining my users to type everytime a captcha because (a would have to do it 30 to 50 times a day). So i want the captcha to be displayed not always.

Hope you could provide me with help.

From the standpoint of preventing spam, rarely showing a CAPTCHA is almost as ineffective as not using CAPTCHA, so I it doesn't make any sense.

However, you should try out the "Persistence" settings on the CAPTCHA admin page. There you can set that once a users successfully answered a CAPTCHA, he won't be bothered with it afterwards. Note: this works only with authenticated users or anonymous users with cookies enabled.

I just thought about it.
It is very inefficiens because a robot could keep trying to spam untill he get a form without a captcha.
Thanks for the info.

The bot would not only try, it would also succeed every time ;)
