From Recent feature changes to Stack Exchange
2014-06-10: When moderators or users with the "create new tags" privilege attempt to create one or more new tags either while asking a question or during an edit they are shown a confirmation dialog to reduce risk of tags created by mistake. This feature is enabled on a per-site basis.
Can the New tag confirmation dialog be enabled for the blender exchange? I think that would be helpful, for some of the tag typos that come along. Example question intoface, not interface.
