Shadow_1

I need help with map editing, I am a first time map editor and I need some advice. I want to incorporate a briefing to my maps but I am having difficulty. Do I do the briefing in a Word document or note pad? Which ever one I use once written which folder do I save it in? Second question, how do I get arty carters to appear on my map? Help from anyone with the answer to these questions would be outstanding! Shadow_1
