Ever wanted to build something fundamental and get it out to millions of folks? I worked for years as an enterprise consultant and that was a very valuable experience, getting insight into a ton of LOB implementations, but nothing beats building the core pieces...

We are very close to the public release of the "Indigo" March community release but there is still much to do. As you'll see soon, this is pre-Beta and there is a lot of feature work, validation, polish and process to push before we hit the V1.0 bar. If you're serious about and experienced in distributed systems, there are openings for developers, testers and program managers.
