Unfortunately we will now have to manually approve user accounts, which means a delay between when you register and when you can post.
Also: the admins at DTA are just getting exhausted by the constant onslaught of spam users and comments. If you would be willing to help us manage our spam we would love some extra sets of eyes. Basically we'd give your current DTA account the necessary priveledges to delete spam when you see it. Interested? Contact us at http://drivetheamericas.com/contact and we'll get you set up. Thanks!
