As we mentioned in this recent blog post, we have switched over to a new tag-based forum system. We encourage you to read the post and see what has changed! The old forums can still be found at http://forum-archive.developer.nvidia.com, but they have no been converted to read-only forums. If you had a question on the old forums that was unanswered, please create a new question on these forums and copy the question over. We will not be transferring user accounts and forum posts from the old system to this new one. We sincerely apologize if this causes an inconvenience!
