If you use both Basecamp 3 and Zulip, you'll be happy to know that there's an easy way to send comment from Basecamp 3 into Zulip. Just activate this automation and it will automatically send a message to the corresponding Zulip channel whenever you create a comment in Basecamp 3.
This can be really helpful if you're working on a project with a team and need to keep everyone updated on what's happening. Plus, it's a great way to avoid having multiple conversations in different places!
