Submit URL confirmation

I just submitted my url for consideration for the ODP but when I pressed the submit button I did not get a confirmation that it had been submitted. There was a large Go Back button so I thought I had made an error in the form. This resulted in me submitting twice, which I read was not allowed. Perhaps a "your submission has been received" response would be good just to know that you are at the end of the line. Thanks.

When a sugegstion has been made succesfull a message is displayed on screen.

When a "Go Back" message is displayed (there should be more text than just the go back) the suggestion was not succesfull.
The "Go Back" can be caused by missing or wrong information on the form. Please correct the form and suggest again.
Or it can be caused by a temporary performance issue on the server. Please try again at a later time.

And if it went through: A duplicate suggestion of the same URL to the same category simply overwrites the previous one, so no harm in repeating.
