HN's Submit page sucks

I really admire HNs design. Its a bastion of elegant pragmatism in an age of bloat and irritating whimsy.. But the submit page sucks. Here are two problems I've just encountered.

1. I try to submit something and it says "Please try again." I can try over and over again and get the same message. Obviously something is wrong here, perhaps the site could indicate what?

2.Theres no link back to the HN homepage, and if I've tried submitting 10 times then I'd need to hit back 10 times in my browser to get back to it.
