Allow submission owner to be changed after submission

Multiple owners would also be good. I could see a scenario where its a group project and they want to add someone else.

when clicking on my add note icon nothing happens. No pop up or anything.

Also any reason it can't be a field on the submission edit tab like similar to a node?

I feel like people are comfortable with that and I could see wanting to provide permissions to allow different roles to change the author.

Jake,

When visiting the log link from within the webform I am receiving the following error:
