If you don't, you can sign up here.
So, interesting notion, probably some of you already know: boosts ("re-toots") can be deleted by clicking on the 🔄 symbol. However, if the boost has crossed the border to another instance, it cannot be deleted from there!
You can only delete boosts from your own instance. They will still appear to your followers who follow you from different instances!
@TQ good to know!
@NinahMarie Thought so, too...
