I'm not entirely sure what you mean, but if you want to document the process as a project log then by all means go for it. If it's suitable for going on the main site and you're willing to submit it then I don't see why we can't do that. Once the game is finished I very much plan to write up an account of the whole thing for an article - how we designed it, the aims, the engine, everything. I'll probably do a quick Q&A with everyone involved and talk about putting my money where my mouth is, ending with the final game available for download.
The project log style thread is a good idea for people to follow progress. Whilst we can discuss things here and the wiki a clear thread showing just progress would be great. Tutorial, also a good idea if you've got time. I've just been going through some XNA tutorials whilst rebuilding my Macbook Pro and a lot of programming from Uni has come flooding back. If you can get some of the basic code down I should have no problem reading it and understanding what's going on.
Good to hear it! Doug's managed to find a library called Mono.XNA which allows XNA to run on Linux, apparently. We're gonna check it out and see if it's worth following up on. Looks decent though.
