Should be good now.

If we didn't have this there would be a stream of spam posts a mile long every day. Imagine we have a bouncer outside who sometimes won't let regulars in because they aren't dressed right.

The server was overwhelmed for about 5 hours, I don't know the cause. Looks all fine now.

Thanks guys!

bobbym - did you compare {900,1100,1200,1000,900,900} to {1000,1000,1000,1000,1000,1000} ? Otherwise Chi-square is 0 (and DF 0 also)

If so I get a Chi-square of 38.7332 and p = 2.68247e-7 , which is quite cool as it shows that to be a very expected result.

So, we can agree here to give them honorary categories of test1 to test6 and random vs boring.
