Yes, the Sovrin Slack belongs to the Sovrin Foundation, not Evernym. Evernym participates but so do many other companies and individuals. If you need an invite, you are welcome to email me. Use my first name (drummond) dot my last name (reed) at evernym.com. If you put “Please invite me to the Sovrin Slack team” in the subject line I’ll do it as soon as I see the message.
