JEvents Locations allows you to create and mantain a list of locations that can easily integrate with JEvents making your Events management easier.
Use Free Input of Addresses or create a structured list of Country/State/City to organize your locations, and obviously, you can also use categories to classify your Locations.
There is no need to type the same location every time you create a new event. Using the locations manager you will be able to share the same location with all your events and additionally, you will be able to show all the events that take place in that location.
