Hi, I have a character "Kale Hearthward" but the tag is misspelled as "Kale_Heartwhind" on E621.

https://www.furaffinity.net/gallery/kalofoxfire/folder/923349/Kale-Hearthward/ (correct spelling)
https://e621.net/wiki_pages/show_or_new?title=kale_heartwhind (the incorrectly spelled tag)

How do I change it?

Since there's only a few posts with the tag, it can be changed manually. Under the image, click Edit, then change kale_heartwhind in post's tags to kale_hearthward.

Also note that the process is:
- Change all posts to new tag name
- Change new tag type to the appropriate type
- Change old tag type to general
- Rename the wiki page, if it exists

If you believe that it will be misspelled frequently, and alias may be better. You can create an alias here - however, how soon it is approved isn't guaranteed by any time.
