Currently the Twitter module has a feature on the Advanced tab that is very interesting (No tweets - The message to display When there are no tweets returned by the search query)
This option is relevant to the Ticker module.
See the example below:
A ticker that returns the name of the company’s birthdays for the current day. There is possibility of the current X (day) does not have birthdays. Rather than treating this variable by XML, we could have this analysis by Xibo, facilitate the user to integrations.
