If you want to cooperate with others on maps, there are multiple options. Probably the easiest one would be first finding a group of players that'd want to collaborate, then use google drive or dropbox to share files. Data transfer is far more complicated thatn simple forum script, so I doubt there'll be an option for that on warlight in the near future.
