 # Slack
 
-We have our very own [Slack organization](https://reactivex.slack.com/) which contains some of the best user interface/reactive extension developers in the industry. All software engineers, young and old, regardless of experience are welcome to join our campfire but you'll need to send an email to [paul@paulbetts.org](mailto:paul@paulbetts.org) with the Email address you'd like to be invited, and we'll send you an invite. Sit tight, it's worth it.
