Private messaging, group messaging, and arbitrary streams
Free, but invite-only
Our community network is small and sustainable. We are tied closely to our users and developers through their donations and optional pay-what-you-want features.
When you invite someone, they are associated with you in the user tree.
The API encourages a high level of transparency and control. You will need a third-party app to do even the simplest things, but there are plenty of options; from Android and iOS to command line and Blackberry.
If you have questions or would like an invite, get in touch!
