to run dungeon crawls online: a map-making template that anyone in game can use. Industrious DMs can make their maps before hand; lazy ones can make it up as they go.
I've included a sample map of a crypt that took me a little over an hour to do (though I use graphic programs every day) and I found Google Documents to be pretty nifty. One quick tip: once you've created a room, group all the objects used. Makes it easier to handle.
First time I've done something like this so if it's got bugs, lemme know (gently).
Go have fun with it; if you make anything with it send me a JPG so I can chuck it in here. Plus if you go all out and make geomorphs for others to use lemme know so I can link'em.
Last thing, there's plenty of free icons out there, specifically for this kinda thing; so if you think my designs suck just go for a quick search.
