Adobe Exchange has a load of free stuff which might come in handy. These Actions could be useful..
there's some colour schemers which I posted in the colour scheme thread.
but there's also this one that cuts up an image into equal parts for printing. If you're planning to work on a super big map and want to cut it up into easier smaller chunks then this might help. I've not tried it yet, so if anyone does please post back here and let us know how you get on? Cheers
