1 Click Browse Files, below, and navigate to the file you wish to upload, then doubleclick the file name, or select it and say “open,” “select,” or similar. Add as many files as you like, even selecting several at once if they are visible in the selection window. (With most computers, you can speed navigation by dragging the file into the selection window.)
2 Add a comment on a file line, if you wish.
3 Click Upload, and be sure to keep the window open until both progress indicators say 100%.
