My delicious account has a great many bookmarks tagged "Bookmarks" - this would have happened when I imported my browser bookmarks into the service. The tag is redundant, and I've worked on eliminating it's use. It's a matter of a few clicks to edit a single bookmark and remove the tag; the problem is that I have over 700 bookmarks with the "Bookmarks" tag. Ugh.
Is there any easy or automated way to mass edit bookmark tags, or even to remove a particular tag altogether?
