It's definitely best to just edit from hosting your own multiplayer, that way you can reload the map from the admin panel and test as you edit. Rogue, if you, or anyone for that matter, would like help getting map-making going, I'm always happy to talk people through it. It's probably best if you come find me on IRC, which I'm usually on. Then I can answer any questions and give advice about what I've learned from this editor more quickly and easily. Nasturtium will probably help as well. Look for us on #mount&blade-crpg channel on the quakenet servers.
