I spent some time this morning going through all the posts here and gathering all the pertinent data to update the Mission Editor Tutorial document originally created by HarryH.
It now contains a history of all the release changes and additional explanations throughout the document. If you keep a copy of this it will be easy to maintain and update as new features are created. I would be happy to assist whenever possible.
It can be downloaded from my dropbox here: MissionEditorTutorial - click here
