What is CubeForge?+

How is CubeForge different from other cube tools or spreadsheets?+
CubeForge is designed around ease of use and, even more importantly, enjoyment of use. Building and maintaining a cube is a long-term creative project. While many tools focus primarily on data and functionality, CubeForge focuses on the experience — making it intuitive, welcoming, and pleasant to spend time in.

Can multiple users collaborate on the same cube?+
