My old code is in the discussion thread of that kata; I solved it another way, but it still seems to fail if I try to use the len() function on that big array with Python.

Can confirm. It works only on the dashboard.

EDIT: On other pages, one can press Feedback and reload the page. Then the Feedback sidebar will pop up. But that's only somewhat reproducible, as the sidebar seems to work randomly.

I'd like a feature to search the forums and the blog.

feedback button isn't a link.

I agree. Not that this tests anything but understanding of String.format. A terrible join test imho.
