Yo #[0], put your profile or an official "Nostrgram" account right in the message about updates so that I can zap you during the few seconds its right in front of me. Every time i have to go searching for you & that's enough of a barrier to probably make 95% of people who would zap, not zap.
In other words, put your profile link or preferably a zap button directly in the update message window.
