Artists: please include your username/signature

We had some issues recently with plagiarism (thanks @stekene for bringing them to my attention). Those users have been dealt with appropriately (including removal from the community).

To help prevent plagiarism, please include your username as a signature on your works of art when possible. Really easy to add to to a painting/drawing. For 3d things, pics that include your face or username (like on a piece of paper next to your art) would be great.

This isn't a requirement to get curated, it will just help me and others figure out when others are copying your work!

I will also pay more attention to this going forward. It's a shame that this is an issue, but such is life.
