Dungeonforge is a map making program. It is very similar to the all but dead DungeonCrafter program. It has a few extra features such as PNG support as well as the ability to print battlemats.
Cool, is this a freeware program or something else? Could I get a hold of the website you are talking about at least so I can go and look up more information on my own about it please?
It's a free tile-based map maker. Great for battlemap type stuff. The website is http://www.dungeonforge.com but like it was stated above, the site is down at the moment.
