Thanks! For clarity I was mostly thinking about the UI pattern in your client app. E.g. if my community currently in Slack has multiple "channels", I can replace Slack with a relay, and the channels with NIP-29 groups, but there may need a visual hierarchy of "Relay>Group" or at least a grouping of Relay1Group1,2,3,Relay2Group1,2,3, etc.

Just musing. Trying to figure out the correct pattern
