1. Register account at exchange that supports trading BTC for NMC. For example BTC-E.
2. Find free Bitcoin faucet, for example https://freebitcoins.appspot.com/, and transfer some free bitcoins to get account from the exchange.
3. Convert your free Bitcoins to some Namecoins!
At the time of this writing, you can get about 0.35 NMC using this method, which is enough to register about 15 domain names.
Namecoins are mined in the same method as bitcoins.
