Yes! Many cities are home to more than one TEDx event and often there are different types of TEDx events for the different communities in that city (for example, a location-based TEDx event for the residents of a certain neighborhood, a school-based TEDx event for students and staff, or an internal TEDx event for the employees of an organization).
Larger cities will often have more TEDx events and we always encourage organizers to connect with one another. If there are several other TEDx events in your city or region, we recommend looking for ways to get together, share knowledge, and keep one another up to date - perhaps by holding a regional TEDx workshop!
