Overview
One of the options to send a GoVideo recording is through the Gmail option in the Sharing Page header. This will bring up a new compose window with the video thumbnail.
Symptom
This option will bring up a new compose window, but it will not render a default signature if set.
Cause
The code for this button is not able to generate the signature in Gmail.
Solution
A simple workaround is to open Gmail first and use the Vbot icon from underneath the compose window.
If you are using GoVideo Enterprise, you can select historic videos using this method, or the free version will automatically insert the last video that was recorded.
