Just a quick heads up that Hiveminder now has support for OAuth. OAuth is a new way for you to safely share access to your data with third-party services. As an end-user, you can safely stop reading this post now.
If you're an application or service developer and have something that you think might dovetail nicely with Hiveminder, now's a great time to get started.
The best place to discuss our use of OAuth is http://groups.google.com/group/hiveminder-api
