The [tag:unlock] tag seems to meet all the criteria for a tag that should be removed - per the [recent tag-cleanup initiative][1]: > If the tag falls into any of these categories, it should probably be removed or replaced: > > * The tag is only useful when it's combined with another tag. Like [update], [install] or [task]. > > * The tag does not describe a specific technology or area of expertise. Like [color], [temporary] or [file]. > > * The tag could mean different things, depending on context. Like [environment], [noise] or [terminal]. > > * The tag describes an extremely broad topic. Like [software], [technology] or [equipment]. No questions have been tagged [tag:unlock], and the tag's wiki is empty. Can anyone offer a good reason to keep it?
