If you are thinking of contributing, you should at least read what it says in the readme instead of pretending that not reading the readme was unfairly held against you:

"For code contributions, it's best to start out with modestly sized fixes and features and work your way up. There are so many different possible implementations of more major features – many of which would cause undesirable code or vision conflicts with OpenMW – that those should be talked over in advance with the existing developers before effort is spent on them."
