Erm I just accidentally sent Bitcoins to myself. It currently has 18 confirmations and the client actually says 'Payment to yourself'.

Couldnt someone make blocks very very large by doing it repeatedly?
It would take a few seconds to make a endless bash loop doing it.

Why can you send coins to yourself?

I've got a idle server which is just running Bitcoin right now, and a couple of days I checked its balance and it had generated 50.02 bitcoins.
I sent it to another account, and it sent fine.

What is with that?
I thought you only got 50, and that was the only way to generate BC.
