I signed up on Steemit and created my first blog. It is much easier than I thought. I have ideas for two blogs. Is it possible to create multiple blogs with one account or do I need to register a new account for each blog?

If first holds, where can I create a second blog?

If last holds, there is a problem with the cell phone numbers. I do only own one mobile phone and thus I can not register again. Is there an alternative way?
