Submissions of all papers to FLAIRS-35 is done through the EasyChair conference system:

When submitting your paper, select the proper track to which the paper is supposed to go. Double-blind reviewing is used for research papers, so submitted papers must not reveal authors identify (for example, use your paper ID from EasyChair instead of author name in your paper). Do NOT use a fake name for your EasyChair login; your EasyChair account information is hidden from reviewers.

The paper submission is a two-step process. First, the paper abstract needs to be registered in EasyChair by the Paper abstract submission deadline. Then, the full paper in PDF is due by the Paper submission deadline. Remember, without registering your abstract on time, you will not be allowed to submit the paper later.

Follow the rules published in respective Call and respect the deadlines.
