This is a detailed explanation of the use and rationale of the tag tagme. For a broad overview of tagging, see tagging guidelines.

This tag indicates that there is insufficient tagging to discover who drew a picture.

This is the most important information for tags to provide: to give credit to the artist, and so when people find an artist they like, they can find out who he/she is. (Discovering an artist you like and being able to find more of his works can be more valuable than the image itself!)

If a circle is tagged, tagme is generally not needed.

Tagme is not necessary for missing character or copyright tags.
