[Suggestion] "Flag for update"Follow

With Wrath of the Lich King out for WoW, and I'm sure other expansions out for some of the other Wiki games (I know EQ2 just had one too, not sure if any of the others), what would the possibility of getting a flag for an article (similar to the "Stub flag") that flags it for updating?

Not sure the specifics of the EQ2 or other games, but at least for WotLK the expansion changed a lot of things and it would be nice if we could get a common way to tell what needs updating. Just a thought :).
