Now I shall present you the updated, extended and finished Coop map conversion tutorial. It should have everything you would ever think about. You do not need to have previous experience of scripting or mapping, aslong as you have a little patience and have a basic skills of learning. It may seem scary at first look, but it is not really that bad (atleast so I have heard 
)
Also now Coop is more Custom map friendly. For example there are fast HTTP downloads and there is a present campaign system that makes playing the maps easy. So maybe give it a go. Couple days and you get to play a map.
