Judging from this you can work from the first 100 responses, it just won't show you the ones after, so to all extents and purposes, voting is closed.
Only the second time that variation has been used. I'm impressed!
Can you not declare the results based on the results as they stood at 100 Bear? (100 people voted....!?)
It wouldn't be particularly enhanced either, do they need the b*llsh*t and pressure?
There are reasons for and against, i'm still more inclined against mind.
