In the training course that I attended, there was a sample
shown of a Revisions Page, which would "automatically" update with
a link to any documents that were revised during a particular time
period. If I remember the discussion correctly, it would hold those
revisions as a permanent copy for the old documents while providing
the most current links. This wasn't part of the actual training
course, just a side note, so unfortunately I don't have any
documentation. Any ideas?
