Authorship is currently in the token sale stage, and is offering a bounty program to get some of their tokens for free if you signup with them (tokens from the bounty period will be sent out at the end of the bounty promotion). They are “Making the Internet More Free and Accessible For Authors and Readers”, basically a decentralization form of the Internet for authors, readers, publishers, and translators to connect with each other and offer their services (how it works). The big impact of Authorship is how it takes a stab at the current publishing industry and seeks to put more money in the hands of the writers actually producing the content, and not the platform (cough cough Amazon), you can see how they are different here.
Your wallet address you enter on signup should support ERC20 Tokens, a good wallet is MyEtherWallet. Here is a youtube video if you need help with the setup process.
Update: They have added an email verification step, so after signing up make sure to verify your email to qualify.
