What is the difference between papers, abstracts and extended abstracts?

You have three options where authors upload by:

1) The abstract box and upload (The paper option)
2) The abstract box only (The abstract option)
3) Upload only (The extended abstract option)

Using the abstract box lets you enforce a word limit, which we can’t do if they are uploading a document. It is important to note that the author will have to complete all steps before a paper can be marked as complete and therefore move forward to be allocated in review – because of this; papers should only be chosen where all authors will be uploading a paper.
