Please keep in mind that any SIN you mine between now and "go live" date is on TESTNET worthless and will not appear in your new MAINNET SIN wallet. The pools have established the ability to test mine X25X prior to launch so we can all check our miners  (and they can test their configurations) - in advance of the hardfork/mainnet launch on May 31st.

FYI - SUQA current block is 165776 - see http://suqaexplorer.com/
So we're 4224 block away from 170000. At 720 blocks/day we're ~5.8 days away from SIN Mainnet launch.
