I'm glad to find out that I should boldy edit the Ubuntu and community wikis, including adding new info to old pages, and that there is even a way to request whole page deletions where necessary.
However, what if a page contains some useful information, and some just plain old instructions? You know those pages that include stuff about Dapper and Hardy and workarounds that (thankfully) we no longer need, thanks to those same brave souls who went before us.
My instinct is that instructions for non-supported releases should not be on the latest revision of a wiki page. Is there a policy for this? If so, should the old instructions be deleted, archived, or something else? If not, is there a preferred way to separate them out?
