Hi guys, new to the whole bitcoin scene and stumbled upon this pool.

Currently mining using GUIMiner on my laptop and mining at 32ish MHash/s (this is slow, right?). I have a couple of questions:

What are shares? Mine is currently showing 10 shares accepted

How and when do I get my bitcoins?

How do I keep track of the transactions?

Will mining on my laptop fry it?

If anyone could give me an answer, that would be great. Sorry, total noooob here.
