Did I submit twice unknowingly?

Hello Editors,

Today morning I submitted http://www.yellowexpress.com.au to:
http://dmoz.org/Regional/Oceania/Australia/Business_and_Economy/Shipping,_Storage,_and_Logistics/

I used Internet Explorer and the submission process went on and on. Neither did the timed out page appear. So I used Opera Browser and kaboom!!! the submission was sent in a flash.

Now what I want to know is: There might be chance that the listing was sumitted twice. Will I get penalized? If so, can any editor help me out in this regard.

Thank you editors for your kind advice and help in advance!!! I have enjoyed availing your assistance for the past 6 months.

Regards,
Dilip Samuel

Don't worry about it. If two submissions were received, one will be removed and the other will remain for review. It won't affect the review of your site at all. Lots of submissions will make us think you are a spammer, but two submissions don't constitute "lots"
