If you sign up on weread.com
and go to your profile, there is a link under your information on the left to "Click here to register as an author". This automatically searches for your author page, and if one is returned for you, when you claim the page it will allow you to update your page and information. We are adding hundreds of thousands of authors soon. If you are not there now, you can create a page or wait for the update and see if you are among the authors we add.
We are also working to expand the functionality of author pages so that you have even more features on weRead to reach more readers. We will have more details on this for you soon.
