Mathspam has been spilt out to a module - https://github.com/silverstripe/silverstripe-mathspamprotection

Thanks,

I did add that directory, and do the dev/build
but how do I use it.

Also, see my post on forms, I think this could be the issue but not sure...

Do I have to declare mathspam anywhere as a varriable like before in _config

Thank-you for your help, I finally got the forms with the new version working and the math captcha now...
