In Ghostview (gv), choose "Seascape" from the orientation menu and 0.25 magnification from magnification menu to view the full page. On a PC (GSView) try "User Defined" option in Media menu with width=900, height=1200. If you want to view the text in the poster, you may need a larger magnification.
Once you have edited your latex file and have a nice "Special Format" size poster, you need to resize file to a size suitable for printing. Recommended size: A0 (roughly 110cm by 90cm). To do this,
poster_resize UFposter.ps S
where UFposter.ps is your postscript file, and S is the scale factor. This should produce a new file names UFposter.resize.ps in which the bounding boxes are changed, etc. You can rename it so that you can remember the size, e.g. UFposterA0.ps. Check UFposterA0 one last time before printing!
With luck, you have a beautiful poster with which to impress your colleagues at the conference in Maui.
