             In the interim, if you haven't already, there's a few things you might be interested in reviewing or confirming:
 
               1. [ ] **Short description**: Tell us a small bit about your tool! We love staying up to date on what's out there, and what your intentions are in writing it.
-              2. [ ] **Common Interfaces**: We maintain a page with some "commonly useful programming interfaces" that tooling may want to implement and present to your users.
+              2. [ ] **Come Join Our Slack!**: We have an `#implementers` channel for anyone interested in or building JSON Schema tooling!
+                      An invite can be found [here](https://json-schema.org/slack) or on our homepage!

                       You can find that page [here in our documentation](https://json-schema.org/implementers/interfaces).
                       Have a read through and consider whether you implement or should implement any of what's there.
-              3. [ ] **Bowtie Harness**: [Bowtie](https://github.com/bowtie-json-schema/bowtie) is a tool which gives JSON Schema users access to a huge number of different implementations across many languages, and [reports on](https://bowtie.report/) the compliance of those implementations with the JSON Schema specifications.

                       If it makes sense for your kind of tool, consider writing a *harness* which connects it to Bowtie. Instructions for doing so can be found in the tutorial in [Bowtie's documentation](https://docs.bowtie.report/).
