I suggest some way to post a shared deviation. A friend of mine and me have an account. He made a drawing, an i will animate it. It would be interesting with we could post the same image, receive the same comments and favorites, and have the same deviation in both our galleries, with our both names on the page, like:
Adding a checkbox to the dA submission page that says "this is a collaboration" Input names if it is a collaboration Send a correspondence message to the other collaborators, and add their names to the dev / ask if they want it in their gallery if they approve it.
Not hard to do and it would definitely be useful! It would also cut down on the amount of double submissions I think.
