I'm starting to consider the possibility of running SoW on RPOL, but don't readily have the facility for doing image maps (especially because while I'm at work I can't load image-maps there). Has anybody converted any of the maps to ASCII versions for PBP use?
The Scales of War (scales-of-war.pbworks.com/FrontPage) wiki has maps for each of the adventures in pdf format on it. I think they were made with Campaign Cartographer. And with them in pdf format, you might be able to print them out easily enough even without image software. Just, it will take a LOT of paper... please at least double side the maps (print one map on one side and another on the other) 
But aside from hand drawing on a large flipchart type pad (which is what I primarily use), not sure if there are other resources.
I've seen those... I'm thinking of ASCII maps for use in a play-by-post game. PDF doesn't work well for that.
