I recently added a contact I knew would have TextSecure, so I was able to verify that this either isn't supported or isn't working.\r\n\r\nI have a suspicion that this might not easily work with the [contact discovery](https://whispersystems.org/blog/contact-discovery/) mechanism, and if so, I can continue creating contacts before texting them."}}
