You may have noticed that you're now asked to register with Guardian Unlimited before you can leave a comment on Technology Blog. It's a system which has been tested on our new cousin, Comment is Free, and now rolled out across Guardian Unlimited's other blogs - including our closely-related Games blog.
You can register here.
The idea is that everyone will have a permanent identity across the site, which should make the standard of debate as high as possible (we often have raucous arguments here, but you wouldn't believe how vicious some of the debates can get elsewhere).
All commenters are expected to comply with our terms and conditions and our talk policy.
Neil McIntosh, formerly of this parish and now Guardian Unlimited's assistant editor, has explained a little more over on News blog.
