I have followed this tutorial to create a custom form
But I am not trying to add a caaptcha and failing.
Under modules -> gallery I have searched and installed "Orchard.Captcha - Version: 1.0.1"
under modules -> features I have confimed that it is enabled
Then under content defination -> content types -> [myContentTypeName] ->edit -> add part I look for a captcha check box but there is not one there.
What am I doing wrong?
