[IMPORTANT] To submit an abstract, authors must create an account first. Then they can submit their abstracts by logging in to their account. The manuscript (full paper) can be submitted only after authors submit their abstract. The whole submission process is done fully online (NOT by email) to guarantee smooth administration. Letter of Acceptance (LoA) and Letter of Invitation (LoI) can be downloaded directly from your account once your abstract is accepted to be presented at the conference.
