+# indico-plugin-i18n-demo
+
+This is a plugin intended for the [i18n demo instance](https://localization-demo.getindico.io). It does two things:
+
+- All emails are redirected to the user who sent them (avoids spamming random people and lets you check email translations)
+- Adds a new **Clone** button to the example events. When clicked, the corresponding event is cloned into your own personal subcategory and you get management rights to it. This way, you can see the management area without accidentally modifying the example events.
