In case you missed it, yiimp is back on line to mine sweepstakes
http://yiimp.euYiimp gone for good due to hack
The Yiimp pools have found the exploit hole and are patching it.
In the meantime SteamOctanePool.com is still up for SWEEP and the holes were patches, as well as extra security added!
Happy Mining!
