Anyone have any experience with Poolwarz.com?
Yes, I've been pointing my desktop (~100kh) to it for a couple weeks now for giggles. I'm not paying the monthly fee, so I don't get auto-switching, I just play with it manually. There is no automatic payout to BTC that I've seen, so I have a bunch of addresses and auto-sell's at Crytpsy. For the small volume I'm producing, it's not too big a deal, but I wouldn't want to bother with all that trading if I had a proper rig pointed at it.
Overall, it's fun to play with, but not really worth the effort, especially when compared to the ease of middlecoin.
