I like the idea, and I was just messing around with the numbers... I like how you made the numbers work out so that the weekly activity is most important.

I was going to suggest making a more rounded number, but this way actually works out nicely.

Quick question: What would happen to Post Count? Would it just vanish into the dark, or would there be a way to check up on it out of curiousity?

I'm going to mess with some numbers now, but I doubt I'll find anything more intriguing...
