Naturally. It's not very hard, it just requires a little bit of effort - as you said, tracking down posts and possibly editing them together in an easy-to-understand way.
Karajorma has asked the project heads to contribute descriptions for their projects. Some have responded; some have not yet responded. We'll probably make another round of requests soon.
But again, we need help generating content, whether it's content from scratch or content that's already on the forum but needs editing together in a form suitable for the main page. Are you interested?
