Haha I had some trouble uploading at first too!
Step 1: go to the upload tab on the bar at the top
Step 2: click on "new story" on top right hand corner of the bar that appears
Step 3: either type or copy and paste form word document or click "upload file" at the bottom right hand side of the empty box.
step 4: make any final changes that you need to , bolding,spell checking, ect.
Step 5 : click on the " I have read and agree to the terms of use and copyright policy. I declare that this material does not violate the rights of any copyright owner." box and then click save and update!
