Firefly feedback

Since Firefly team maintainers are mostly from Kaleido, they mostly use Slack for internal messages. Onboarding the team onto Rocketchat and messaging in teh open has been a challenge. 

Since launching Hyperledger's Discord, the Firefly team has been using the Discord channel and have had a great experience. All conversations have now been happening in the open and they are pleased with the user experience. They like threading feature and notifications on phone. They even use the ephemeral thread feature. Team is hoping they can continue to use Discord and migrate their external community (non maintainers) on it.
