Yes, at least the first couple months would be spent on developing a solid design document, followed by the software architecture. During this time, I will be spending a great deal of effort on developing the website and the process by which people will be able to access the files.

I've seen several people mention that their drawing skills aren't up to par. You can still be a part! Once the game has been designed and the programmers begin working on the code, they'll need graphics as soon as possible to start testing and tweeking things. Regardless of how bad you think your drawing skills are, most programmers are worse. Much worse. Anyway, we won't need production-quality artwork at first.

Keep those general storyline ideas coming, or further develop the ones you like!
