The "If you're unable to fix the issues, please open a question on our meta discussion site." link on the Network Login Troubleshooting page does not work.
It doesn't work because there are two http://
in the link. And at least Chrome turns that into http://http//meta.stackoverflow.com/
if you click on it.
That's the href from the site source:
<a href="http://http://meta.stackexchange.com/questions/ask?tags=chat&title=Network%20login%failing">our meta discussion site</a>.
Maybe someone could fix that.
PS: If you don't see this link, you are not having problems with the log in ;-)
