Competition submission materials should be kept in the project folder. This applies to current and past projects.
Under the current template folder scheme, create a folder in 2 Output called 'Competitions'. (The zTemplate folder, as of now, already has this.)
Under the old template folder scheme (01CDs, 02 Reference, etc), create a folder called 'Competitions' at the top level.
Within the Competitions folder, create a folder for each submission, giving the name of the competition. Example: 2 Output / Competitions / Remodeling 2006/.
All files pertaining to the submission should be in there: PLNs, layout books, images, PDFs, forms, etc.
You'll be glad you did!
