If possible, client tester please.  I can test on Linux, if that helps at all.

Hey guys, I've been mining for a while but just got around to registering for an account here.  My question is regarding shares and how they work in reference to mining.  In a pool, how exactly do shares work?  What are they exactly?  It seems to me that they determine how much of a block you get, but I could be wrong.  And you obviously don't get the full block, even if you discover it, right?  Thanks for any answers.
