Hello all,

I'm pretty new to this whole bitcoin mining thing, but I've just recently gotten my rig set up for mining Slush's Pool.  I've been running along for about 30-45 minutes now at ~45 MH/s, and I'm getting a little concerned that my Shares are still set at 0 accepted.  Is this normal, or does it sound like I've gotten something set up incorrectly?  Thanks for any help!
