I don't think I need to write strict rules but there are a couple of guide lines

1. Don't grief
2. Be friendly
3. Don't cause Clank
4. Name your grids
5. Name ALL Pistons and Rotors
6. Once you have built something Press "Shift+F1" if something is showing
in red , it is likely to cause clank.

7. Most importantly have fun

The guidelines above are designed to make your experience better.
without these guidelines, the game will lag and be difficult to fix.
