Alternatives To SourceForge For Open Sourced Projects?

Bowie J. Poag asks: "I'd like to start another project, but I don't want my work hosted on SourceForge due to security concerns. Specifically, I'm looking for someplace I can develop ideas with a small team of people in complete privacy without having details of our development process on display to the general public. Are there other project hosting services available to the community?"
