Hi all! I have a brand new sona! I also have a ref sheet for him made by a brand new artist! How would I go about tagging them both in the sheet that I uploaded? I tried creating the artist under the artists tab, but it didnt seem to work, and I have no clue about the character.

You have to use the tag index to change a tag's type. Creating an artist page does not change a tag to the artist type.

I have taken the liberty of changing the tags' categories for you; kason is now a character tag and whale_pail is now an artist tag.
