If you want to upload your item into a specific section, all you need to do is select that section during the upload process. You can follow these easy steps to do so!
1. Start your upload using either upload button on your profile page or in your header.
2. Follow the document upload process as usual. You'll get this screen below next.
After you have uploaded your document or clicked "No File to Upload?," you should come to the screen where you fill in the information about your document. You can then use the "Sections" drop-down to select what section you would like to upload your item to.
Then, just continue uploading papers as you normally would!
