Where do I go to place an order of 50, in the US?

Starting a business to exchange Bitcoin with PayPal by only accepting irreversible transactions and only offering reversible ones does seem very suspect. It is always better to have multiple options for using your Bitcoins, which can only make the Bitcoin ecosystem stronger, and I hope that this is legitimate.

Bitcoin-qt might minimize to system tray. Does it say "Cannot obtain lock on data directory ... ... Bitcoin is probably already running." when you attempt to open it again?

Well, in that case bitcoin is already running, like it says. All you have to do is open it from your system tray, which is located at bottom right of your screen should you be using a Windows OS of some sorts.

4 hours of active reading I think. I Don't see the clock moving when I do something else

I think the general argument (from what I can tell from reading the newbies subforum) is that not everyone has 4 hours to actively use the forums. Sitting still on a single page for 4 hours does not constitute visiting for 4 hours afterall. The site says it's 0.01BTC which is about $1 right now. I've seen people pay 3 BTC just to troll me personally and some people pay 50 BTC just to run libel campaigns against Ripple, so obviously everyone here values things differently.
