Finding the e-mail address of a video submitter
When someone submits a Hug (video) to your Group Hug, they are prompted for their e-mail address. This is an optional piece of information for them 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 a white "gear") button on the top-right corner of the video.
With the More Options menu open (see above), if the Mail icon is enabled, you can click it, and the e-mail address associated with the video will be temporarily displayed and also copied to your clipboard (to be pasted into your e-mail client, for example).
If the mail icon is disabled, this means that the submitter did not provide their e-mail address.
