How to remove the copyright box on a paper that uses the ACM sig-alternate.cls class file?

Commenting the words in the .cls file won’t help, since there will still be a “blank space” in the bottom-left and my paragraphs won’t fill in.

I don’t know why it took me so long to find the answer by Googling, but this simple one is the solution that worked for me:

Just add the following 3 lines before \begin{document}:

\makeatletter
\def\@copyrightspace{\relax}
\makeatother

Concerning the ACM SIG Proceedings Templates:

• Is it (easily) possible to produce page numbers when working with
  \documentclass{acm_proc_article-sp} or 
  \documentclass[preprint]{acm_proc_article-sp}?

I found no (obvious) way of doing that (looking a bit into the style file). For final versions having no page numbers is reasonable. However, for submissions (in ACM conference format) it might be helpful to be able to switch on page numbering (for instance, for the referees)!

Also an analogous question for the prescribed 9 pt font:

• Is it (easily) possible to produce e.g. 11 pt font (for ACM conference submission versions)?

Answer:

The templates were created so as to, at a minimum, produce a uniform Proceedings. We are not in a position to alter the templates for other purposes, such as refereeing nor do we endorse any changes. 

Using the new style

The new class file defines all the same LaTeX macros as the ACM template, so please read the ACM guide at  http://www.acm.org/sigs/pubs/proceed/sigguide-v2.1sp.htm  first.

Mike's class file has the following differences from the ACM one

• It doesn't load any of the utility packages, specifically, it doesn't load epsfig, amssymb, amsmath, and amsfont. You can load these yourself with \usepackage{epsfig} etc.

• It depends on David Carlisle's pslatex.sty package, found on any CTAN host. You can, for example, find a copy at ftp://ftp.dante.de/tex-archive/macros/latex/contrib/supported/pslatex/.

• It conforms to LaTeX2e's NFSS2, so there aren't any font-changing commands specific to section headers, like \secit{} etc.

Here are few other points about the style.

• There is a preprint document-class option. Say

    \documentclass[preprint]{sigplan-proc}
  

  It only switches off explicitly doing \pagestyle{empty}. By default this just switches on page numbers, but it also gives you control over page headings. For example, you can say this in the document preamble

    \pagestyle{myheadings}
    \markboth{Fred Bloggs}{Draft of: \today}
  

• Ideally, the preprint option would add a date to the title page, but it doesn't yet. I add

    \subtitle{\today}
  

  to do the job. (The subtitle command is documented in the ACM guide.)

• You can suppress the ACM copyright info, and replace it by something else, by saying

      \toappear{Submitted to the Wobble Workshop 2007.}
  

  This is useful for drafts of papers not yet accepted for publication.

• You can suppress the entire ACM copyright space by using the nocopyrightspace document-class option:

    \documentclass[nocopyrightspace]{sigplan-proc}
  

  This is meant for when you want to typeset other papers or drafts that are not ACM copyright and don't need the space.
