Oh and can I ask please... All my coins are deposited now.  Do I have to leave the wallet running for 12 days?  Or can I close it from time to time when I need my PC to do other work?

Also as far is mining...  I mined for 4 hours and got nothing.  What is the difficulty now?
I mined at CPU speed of about 300H/s...  Nothing in 4 hours... Should I go back to pool mining again?
Or stick with it and try to nail a block? What are the odds of a block today?



Thanks,
Bob
