One of the major issues I have with SilverStripe at the moment is the complete lack of a fully integrated user registration system. In the current environment with so much User Generated content it really limits the things one can do. There is no way to use the CMS to make a highly user driven community with out doing a lot of hacking.
Is there any thought of making a complimentary login system? I know I can hack the Forum login system, but I want, dare I say need something that the CMS understands natively, so I can define content as user submittable and user editable.
