Adding a friendly or short name for an event

You can use the redirection tool [Tools > Redirection]  to create a shortname to publicise an event e.g www.worldenergy.org/events/WELSMexicoCity

Using the tool add a redirection as follows
Source URL: /events/WELSMexicoCity
Target URL:/events/2716726e-2cb6-e611-80c3-00155d0511bf/
