Hia, I’m a little unfamiliar with how I can change a my oc’s name from a tag to a character, I have a couple pieces up for her and they all have her name Zoe_(Kinjagh) as a tag, would anyone be so kind to tell me how I can resolve this ^^

If you click the '?' next to a tag, you can access it's wiki. From there you can click on the 'edit tag' link to change the tag category if needed.

From memory, this option is only possible for tags with less than 100 posts for normal members.

There's literally pinned topic explaining this: forum #283267
