Some food for thought...
If you answer my questions in a clear, consise, manner, with as much detail as you can, I would be willing to assist in updating and maintaining your mapping documentation for you.
If you question my abilities I would be more than happy to present the many pages of design documents and documentation I have produced for MVPB as reference.
But, if you choose to allow me to update and maintain your mapping documentation, the details you provide me here would be invaluable towards that task!
