What about azimuthforum as the name? That represents the community here as a group, and is clearly identified. People could create folders for projects that they work on, as they would emerge over time. We should be able to mix codes from different languages in the same projects -- the division by languages can take place as folders within each project.

We should avoid anything that would imply a possible proliferation of repos. And creating too much structure in advance of actual activity (I have learned this the hard way).

This way we can keep it simple, with room to grow.
