You may contact the SPAA secretary with questions about the electronic submissions process when other avenues fail.
Submitted manuscripts may not exceed ten (10) single-spaced double-column pages for regular papers and two (2) single-spaced double-column pages for brief announcements, using 9-point size font on 8.5x11 inch pages, including figures, tables, and references. See http://www.acm.org/sigs/publications/proceedings-templates (Option 2) for details, including the sig-alternate.cls style file and a sample file. Additional details may be added in a clearly marked appendix that will be read at the discretion of the program committee.
Please indicate in the title of your manuscript whether this is a regular paper or a brief announcement. If requested by the authors, a manuscript that is not selected as a regular paper will also be considered for the SPAA brief announcements. Such a request will not affect the chances of the manuscript to be accepted as a regular paper.
