Gregory's Server@ilyess I think the way they've implemented usernames is near perfect. It's super easy to get any username you want if that's important to you as long as you don't care about the numbers on the end. And being completely disposable means you don't have to worry about protecting it.
@jp Yeah, really props to Signal for this implementation. The naming could’ve been better IMO but other than that, it’s flawless. It took them forever but I do appreciate how much thought and careful design went into it.
