The Wiki is about building an encyclopedia of Geomag models, with pictures and instructions for how to build, and counts of the parts required so that people can easily choose models to fit the size of their Geomag collection.
If you've not used Geomag bars and balls before be warned this can be an addictive pasttime, and almost everyone says "you never can have enough rods".
If you have got any models to share, just start creating pages with your creations: lets worry about organising them and getting a standard look to the pages once we've got a hundred or so ....
So for the moment - free for all - no guidelines: I suspect a natural structure will emerge.
Here are the initial comments from the community (we won't need this information soon) these people all came from the Geomag forums hosted by the manufacturer:
