I use Pixlr, which is a free website. It's not great for complicated maps but it's perfectly compatible with Worlda. It's also pretty simple, just use the one pixel paint brush to draw borders. If you do plan to use this and need help just ask me.
would you still be able to provide an easy how to guide - I want to create very simple map - western Europe with sort of actual borders and maybe to be able to add 'nato' style army symbols
any suggestions for a newbie map maker gratefully appreciated - the main effort will be on the AH narrative rather than the maps
