Sure thing

I'll probably buy 2 or 3 shares, i'm 15 so I don't have to much money to spend

Where are you planning to host the miners?
I was kidding about buying more than one share! Also, especially if you're 15 take care not to spend more than you can afford!
That being said; I'm looking at a datacentre below Rotterdam this Friday. Also I can't make any 100% promises on this cause the datacentre owner will have to agree to this as well ofcourse

We might have to transport you there blindfolded

Cheers
I know you were kidding, but I was planning on buying more than 1 share anyways.
It's probably best of you knock me unconcious before you bring me there so as to not compromise the secret location

On a serious note though, how much Gh/s will 3 shares buy me?
Well, with KNC's announcement of this afternoon; a Jupiter will hash 400GH. So currently one share should give 400/248 == 1.613GH, three would give 4.839GH
