Can anyone answer this question: Our group has just delved into VTT's, specifically Maptools, and I'd like to know how I can determine/alter the default grid size in Dundjinni (in px) so when I import it in to maptools the grid is the correct size? Changing the default size for Maptools is fairly easy IIRC.

I use a Mac running OSX 10.5.8 if that makes a difference.
