That brings up a pretty valid point - has anyone broken down what happens with what level of karma?

I know at 5 you can downvote comments, and at 250 you can change your bar color. Somewhere in there, you can create polls, but I don't know how that works, so I don't know what level karma is needed.

I'm pretty sure I could downvote from 25. Maybe it was originally 5. (seeing as I joined much later than you)

I'm at 408, and I can't see a way to start polls, so I'm guessing that's at 500.

You're probably right about the 25 - I'm still pretty new and my karma is at 17, so I don't see downvoting. I hope the minimum number doesn't keep moving up on me as I approach it :)

It's 21 to down vote. I recently got that ability.

It's possible that it has always been 25... I've been wrong before, and I'll be wrong again ;)

Those who know won't tell. And those who tell don't know.
