  ## Read-only view
  -Zulip by default requires an account for interaction, though this "bug" is being
  -actively worked on by the Zulip developers. We currently maintain a read-only
  -view of the Zulip at <https://zulip-archive.rust-lang.org>; this has relatively
  -up to date information (we update every 5 minutes). If you're linking to Zulip
  -from a GitHub comment with the intent to leave a permanent link, this is a good
  -place to link to. There is not currently good tooling for generating the links.
  +Our Zulip instance has the web-public streams beta feature enabled, and we use
  +it for all public streams. Please let us or Zulip developers know if there's any
  +problems with this. The previous solution to the web-public view was the zulip
  +archive, which now redirects to the web public view.
