Thread:Project:Support desk/Removing spam protection

Hi, I don't know how it's called and can't find anything in my searches. When somebody who is not logged in creates or edits a page he has to enter the result of a calculation.

This feature is not required in my case, my wiki is pure intranet where I know the IPs. And I want people to encourage to correct typos and false information.

Can somebody please tell me how to get rid of this calculation box?

Thanks in advance.
