All tasks of the project are a huge effort. That includes coding, both fixing and creating
new features and missions, documentation, website, communication, promoting and more.
So realistically the only way I can see this project keeping its edge is to transform it
into a team project at the first step.
Of course there must be a basic agreement how it will work. Coding standards and proper
documentation are very important parts of that.
Even more a cooperation with the PVP script pack of sbsmac and Devastation
by Dr Eyeball is the way to go.
Finally the Server side only script addon approach, if working, would allow the system
of an unified team approach made library back end for any type of mission.
So the back end is coded in a team effort, and the mission is only used for configuration
(mission type, zone, units basically).
