Hi, I have recently just made a [Uservoice suggestion](
http://warlight.uservoice.com/forums/77051-warlight-features/suggestions/2838331-allowing-open-seats-for-testing-games) for allowing open seats in testing games. I feel this would be easy to implement and allows Real-time game testing. This would be great for me and many other map makers as it allows us to do more tests and test RT, as I play mostly RT.
Here is the description...

"Every map maker has the problem when they want to create a real-time test game. But because you can only invite people to play in Multipayer, you can't co-ordinate a real-time game.
Allowing open seats in test games would change this. You could test the map, find out what you wanted to know and change the map immediately, straight afterwards without having to wait multiple days to test it in Multiday games.
To distinguish the Test games from other Open Games, their Game Name could be highlighted Green with *TESTING GAME* written by the side"
