Btcguild is the pool, and it looks like there is autopayout setup at 8 BTC. User ID 431474. Nothing wrong is here. But what is wrong is total lack of info regarding changes and status. That's really not professional way that shareholders need to track everything and make guesses.
Price dropped becuse price of 1GH at cex.io also dropped.
I completely agree with you the manner in which this was switched over has been unprofessional. Hopefully a status report will be posted soon some transparency would be much appreciated.
