How to enable freecap captcha?

Hello there,

I installed bitweaver 2.7.0 and it works fine.

Now I wanted to enable Captcha for registration.
Therefore I enabled "use freecap" in "Administration > Liberty > Liberty-Settings". But there is no Captcha at the Registration-Page.

Are there more Settings, I have to do?

Please help me.

Thank you

I think captcha only affects posts, you use 'Prevent automatic/robot registration' on the login settings for registration. Not that I have used it ;)

Oh, I am a fool.
I checked the Settings thousands of time, but I did not see this Option.
Thank you for the tip.
