Hey! Let's all bombard the new person with rules!

- Assign each forum with numbers between 4 and 78
- Multiply these numbers by a half of them divided by a quarter squared
- Divide them all by 7, accurate to two decimal points.
- Add them all together, and find the square root
- Only post in forums which originally had a number lower than the square root.

In case you bothered to work all of that out, the answer is: Turquoise curtains.

Oh, hi by the way.
