Starting a new Bitcoin service? Coding up a new app? You DID work out the bugs, right?
Be sure to test your new app on the Bitcoin testnet. This helps you ensure that you have gotten all the kinks worked out before you go live, without having to use (or potentially lose) any "real" Bitcoins.
Thanks to a bunch of work I've been doing, I now have a somewhat sizable quantity of testnet coins. Keep your miners mining BTC and I'll supply your testnet coins. 0.05 BTC for every 50 testnet coins or 1 BTC for 1000. Orders in multiples of 50 please.
