NOTE! This isn't official, merely well-informed
We don't yet have the template information for HICSS-40 (2007), but I assume it's going to look a lot like the HICSS template for the past few years. I'm putting a copy here so people can take a look at the formatting guidelines that have been published by HICSS in earlier versions of the conference.
By the way, although the guideline doesn't mention it, HICSS papers tend to run 10 pages or less... Please don't pad your paper with less-than-stellar prose just to make it ten pages. Trust me, an 8 page paper that's well-written has a better chance of acceptance than a full ten-pager with two pages of drivel stuck in the middle.
