The strategy guide section sounds like a good idea mate, concider it added.
The older missions can be put up if they are not scans or pdfs of the original books or taken word for word from the books because of the IP violation issues. Links to sites hosting them online is probably a bad idea as well.
However, if someone were to recreate them for 3rd edition, changing the wording and maybe using the tile system to recreate the maps then it wouldn't be a problem.
So a redux version of the original missions and campaigns would be ok.
