you guys should really check out mappie. here is
its website. I used it to make the map for stormhold (well, i didnt make the stormhold map image but i sent the drawing it made to someone else that made the actual map image) but still it works great. you can set what it looks for when you are starting a new line, so when you are in game you could just have a macro like "/em starts a new line" and then when you import it you tell it what to look for when you start a new line and you just type "starts a new line" and then it knows to start a new line every time it sees "starts a new line" in your log file. Just make sure you set the grid display type to y z or it wont look like a zone and it will just look like scribbles.
