Finding the e-mail address of a video submitter
When someone submits a Video Clip to your Group Video, they are prompted for their e-mail address. This is an optional piece of information to provide; they can fill it in or skip it. If they do submit their e-mail address, it becomes associated with that video. To see whether there is an e-mail address associated with a particular video, push the More Options (looks like three dots on the right side of the menu bar below the video thumbnail) .
With the More Options menu open (see above), you can click the Copy e-mail address option. The e-mail address associated with the video will be temporarily displayed and copied to your clipboard (to be pasted into your e-mail client, for example).
If the menu says "No e-mail provided", this means that the submitter did not provide their e-mail address.
