To do so, login to the BACKEND control panel, located at www.yourdomainname.com/administrator
Fill out the form with the location information.
Click the save button at the top right of the screen.
Now when you create a new event registration, this place will always show as a place you can select from in the dropdown menu.
Note: You do NOT have to add your location information through this part of the software. Only go to this menu item (Components >Attend Events > Venues) if you want to add a venue you will be using alot and don't want to keep retyping everytime you create a new event registration.
