Is there a reason the Registration Know it All Blog post is protected? Is there a reason my password won't let me view it? It's easily the most important information source currently available outside of the event list.
The blog is meant as "our space" as the Con organizers to put out information without commentary. For the same reason you can't go to Ford's website and comment on their front page announcement about a new model year F-150. These forums, direct email, or the official facebook page for the Con are the right places to discuss or comment. Not sure about your not being able to view the blog post. I'll ask Thomas to take a quick look.
It's doing the same for me, too! Somebody bumped something. Those posts should be public, not requiring a login.
