I am going to submit a paper to the journal of ACM Transactions on web, there is an option for attached files named "File for reviewers". I guess it is the option I should choose, but I don't know in which format the file should be. As I searched the site there are a word and a latex templates for articles, but they might be for the final version of the paper?
Can I submit it as a unformatted word document, but enhanced for reading? or a pdf but not based on the template on the site? by the way, I found their template awful for the reviewing purpose.
