Thatβs not the same thing as the nostrgram everyone uses. The insecure client is called anigma, it used to be called nostrgram.
And where's that client? π
#[7] is the developer for nostrgram.co
Anigma.io is the client that should NOT be used
Yeah Anigma had changed it's name before I ever started coding NostrGram.co. NostrGram uses none of its codebase. Never has. It's completely different. I'd never heard of it when I started coding NostrGram.
