Migration Notification

Brendan OSullivan <bosullivan@...>

Greetings Hyperledger community!

The Linux Foundation has connected with a new vendor called, which provides mailing list services in a simple but modern interface. offers all of the capabilities of our existing Mailman mailing service plus additional community tools that make it an exceptional service solution.

We are planning to migrate your existing mailing list archives and user lists to on April 18th starting at 9:30am PST.

The migration will include details on subscriber preferences and owner or moderator privileges.

During the migration window you will still be able to access the archives, however the delivery of messages sent to the mailing lists during this window will be delayed until after the migration of the archives and list members are complete. We will turn off new list signups during the migration window, then this functionality will be restored once it is complete.


What are the key differences between Mailman and

  • has a modern interface, robust user security model, and interactive, searchable archives
  • provides advanced features including muting threads and integrations with modern tools like GitHub, Slack, and Trello
  • also has optional extras like a shared calendar, polling, chat, a wiki, and more
  • uses a concept of subgroups, where members first join the project “group” (a master list), then they choose the specific “subgroup” lists they want to subscribe to

How is the experience different for me as a list moderator or participant?

In many ways, it is very much the same. You will still find the main group at your existing URL and sub-groups equate to the more focused mailing lists based on the community’s needs. Here is an example of main group and sub-group URL patterns, and their respective emails:




What is different is’s simple but highly functional UI that will make the experience of moderating or participating in the community discussions more enjoyable.
