Just to clarify, your revised proposal should consist of three parts:
- Revised proposal text in which you procesed the reviewers’ comments (5 pages max using the ACM template)
- Response letter in which you detail how you dealt with the reviewers’ comments. For example if a reviewer misinterpreted a part of your proposal, state this and say you have rephrased the text etc. (1-2 pages, up to you how you format it. Do start and end with a salutation as you normally would in a letter)
- Poster (1 page)
Resubmit your revised version as a single pdf to the Easychair system before the deadline.
