File Approving

Hi i uploaded my King Kerching classic layout about 2 days ago and I was thinking....How long does it take for a file to be approved before it is able to be made public?

Now i know it may be down to if the admins are busy or not But that also raises the question. Are these retrictions removed after releasing a number of files?

I am not moaning and i understand if people are busy, i would just like to know for future reference

Thanks
