When you log out it has to go somewhere. Generally I think a lot of places send you to the log in screen because if more than one person uses a computer often the main reason to log out is so you can log in as you rather than the other person.When you hit the back space it does looked like you are still logged in, but I think the browser is pulling the webpage from its memory rather than getting it new. Refreshing the page makes it (for me) go to the visitor page, as does closing and reopening the browser (when I don't re-enter the log in info when it goes to that page)
There is another thread on this forum with all the DAW levels listed. It is based on your post count.
