Question: How do we go about fixing a misspelled tag?
The "n" and "g" are flipped around

Answer: 
Since there are not that many questions tagged with it, I would retag them with the correct tag.

When there are no more questions using a tag it will self destruct in a day or two
It will be deleted automatically at 3:00 am UTC so long as there are no posts tagged with it.
