+## Mailing Lists
+
+The nostr ecosystem is getting large with many different organizations, relays
+and clients. Following the nips repo on github is becoming more difficult and
+noisy. To coordinate on protocol development outside of github, there are
+mailing lists where you can work on NIPs before submitting them here:
+
+* [w3c nostr community group][w3-nostr] - [public-nostr@w3.org][mailto-w3] - requires signup
+* [nostr-protocol google group][nostr-google-group] - [nostr-protocol@googlegroups.com][mailto-google] - no signup required
+
+[w3-nostr]: https://www.w3.org/community/nostr/
