I accidentally found this page: http://bugs.meta.stackoverflow.com/
It looks just like the normal Meta. Upon the second look, though, I noticed that all questions there have the bug tag, on the main page and in search results. Is it just Meta filtered by tag? What happens if I post there? (I posted this via
bugs.meta. It seemed to work fine. The question didn't appear on the main page, as it isn't tagged bug)
Who and what is that page for? How can I use it?
