The submission sites would require you to sign-up using your institutional email. You are also supposed to mark conflicts for each submission.
During the submission process, authors should mark conflicts with any program committee members whom they have collaborated with, in any capacity over the last two years including previous collaborators, advisors etc. Individuals with the same institutional affiliation as yours also count as a conflict.
Papers will represent archival journal-type submissions, with a length of between 4 to 10 pages plus references. Papers submitted to this track should represent polished, significant contributions. Authors are encouraged to submit a paper of length proportional to its contribution.
Posters will not be archival and are intended to allow presenters to share their latest results or get early feedback on projects. Poster submissions will be limited to 2 pages plus references. There are two poster submission deadlines (March 15 and May 15) to allow for earlier travel planning as well as late-breaking work.
The papers and posters should be submitted using the ACM Proceedings New Master Template. The template is also available on the ACM Master Latex Download page. The two column paper format has to be followed for both papers and posters.
For other queries, they can refer to the ACM Master Template Format page.
