We’ve just uploaded a new video tutorial that shows how to update the photo associated with your ProposalSpace profile. Check it out.
We’ve just posted a brief tutorial on YouTube that explains how to review submissions in ProposalSpace: http://www.youtube.com/watch?v=QTWIBReUifc. If you manage a call, you might want to have your reviewers view the tutorial before they get started so they know what to expect.
If you have any suggestions for how we can improve the tutorial—or would like to see us create videos for other topics—just let us know!
