Accepted shares won't go above 200 I'm new to Bitcoin mining, but I'd like to think I got things set up. I'm using guiminer, on slush's pool. For some reason, my accepted shares won't go above 200. 

I have no stale shares but my accepted looks like 1597 (200).

Why is that?
The first number is the number of shares you have solved. 

The second number is the number of pieces of work that you have recieved, but haven't begun solving. If it drops to 0, you aren't mining. Every ten minutes or so, these will become obselete, and you'll need new work, so there's not much point in requesting a bunch ahead of time.
