Trevor, that’s a tough question to answer here because it is broad, could be complex, and you say you’re not the best with MSP. It all comes down to what you want or want them to see. It could be as simple as a custom field or two and some filters, to creating a master project with the appropriate linkages. I’d start with option one and some filters but it sounds like you started with that already. Maybe somebody else can provide some better ideas. I do remember a blog or video some time ago with some good information on how to manage a large project. In fact it might be from MPUG. Have you searched the archives for articles and/or sessions on this topic? Sorry, wish I could be more help.
