I 100% agree with you and support this, Shelley! This is extremely U.S.-centric and for an international organization like mine, making a change would be extremely helpful. And it's not only with the "Events Basics" tab, it's also with member registrations as the "United States" is the default country for personal and organization information. As such, this truly negatively affects the accuracy of our member data if members do not pay attention to it during the registration process.
I highly encourage YourMembership to change this.
Thanks for bringing it up!
