I agree that there are
a very few locations that are undated. However most of the undated downloads are for RTMM PROJECTS like CIRP. BWEP, Alaska Power Project etc. the link will take you to the downloads for those projects.
With the number of download files and only one person handling the site (Doug) there are doubtless times when something got by. I'm sure if you want to search out and list the files you believe need correcting date wise Doug will add them to his 'to do folder' and correct the error.
We believe in putting folks to work slyly and before you know it we got ya hooked on RTMM
