never mind
Q: Crap! I made my map too big/small. Is there a way to change the size?
A: No. However, what you can do is make a stamp of the whole map (use bound box) and check all the boxes. Now drag to cover the entire map. Now make a new map of the size you want and then place the stamp. Two things to note, first, bound box stamps can only be rotated in 90 degree increments. Second, the height may be wonky when you paste your map stamp.
