Version is indicated in .mapinfo along with the other information that the server pulls from map, like author and description.
That's not really my point of this thread through. The problem is moreso that when !map Titan is used, it would be sensible to pick the "titan" currently featured/matchmakered/whatever. Using !map Titan currently picks an undownloadable map.
I'm not saying that preference should be given to newer maps, as that is currently undesirable for some maps like Fairyland. But preference should be given to the ones featuremakered.
A map level that can be used to make maps unpickable on hosts seems like a good idea.
