I know this must seem a stupid question to non-newbies, but I have a few bitcoins and I want to support the network to protect my bitcoins. If I constantly open my bitcoin client is it contributing anything to the network? (I'm not mining or anything, and I read somewhere that it's just miners who check the validity of transactions - or at least that's the impression I got.)
