If your speaker/moderator is being asked to log into your Glisser account, this is due to one of these reasons:
You did not click on the clipboard symbol to the right of Live Control Panel. Please ensure you send the copied link that is generated from the clipboard symbol.
They are trying to access the moderation link on an incompatible browser (for example, IE).
They have not been provided with the entire moderation link. A long link is generated and please ensure they have the full link.
They did not create a guest account with the 72 hour limit.
In all of these instances you would need to re-generate and re-send the link.
