Dear Sir/Madam

I am writing to you today to express interest in merging code into your Free and Open Source software project. The changes I am submitting contained within this pull request consist of a number of additions to your file hosting software that will enable it to display the progress of a file being uploaded to the user. I have attached the requisite files below for perusal at your nearest convenience.

Looking forward to hearing from you. Kind regards, rdqsr
