I have been cleaning up tags on SU today and accidentally created a new tag by hitting return when the tag suggestion drop-down highlighted the tag I wanted. I probably should have pressed tab instead....
Anyway, I would like a confirmation when a new tag is created, both as a way to avoid stupid mistakes and as a place to add a few pointers on tag creation.
Tag FOO does not exist, are you sure you want to create it.
Please make sure that
there isn't an existing tag or sets of tags that can be used instead.
there isn't an alternative spelling already in use
