2du is a city-wide Alerts Club with MANY companies participating.   To keep things organized, EVERY message starts with the CLUB ID for a particular company (or organization or band).

For example, "2duSC14" is the Charleston Grill In South Carolina. So all you really need to know is that this company is "14" !  Both "2du" and the state designator (SC) are obvious to locals.

Now that you know the Alerts Club number for this restaurant, there are mobile commands that you can use to control the Alerts from this company.

For example, the following is how you join the Charleston Grill Alerts Club:

Text "2duSC14" to 39044
