Is there a way to...

[Taloncigar]

For what I know in years of WF mapping it is no possible to copy and paste (or 'append') a map into another, while it is possible to use such a shortcut into the OOB editor.
As for the resize, Jason, I am quite sure that there some kind of limitation in the size since I was never able to create a map larger than 510*600 hexes. If I try to go over this size, the program crash. I am not sure 100%if it is an hardware (resources) or a software (program) problem, but I think the second is much more probable.
And anyway to fill a 510*600=306.000 hexes map you need quite a lot of work...I know it for sure...:-)
