Note about the ether faucet: unfortunately it seems that the Ethereum gas price is very high right now (https://ethgasstation.info/) The server is programmed to provide 0.008 ETH, which under normal conditions is enough for the tx fee, but due to the high gas price you might encounter an "insufficient balance" message when confirming the transaction to create your ID. If that happens, please wait a little while until the gas price comes down a bit and try again.
I should add that using Satellite only requires writing data to the blockchain when you signup. Once your ID exists you can use it to sign things that you post, and that doesn't cost anything.
