Add a new page in your blogger account is not a problem anymore. You are no more required to purposely create a post as a page which I did it before. In other words, you can create a page with a link like http://xaivierchia.blogspot.com/p/about or http://xaivierchia.blogspot.com/p/contact.
All you need to do is:
1. log in http://draft.blogger.com instead of http://www.blogger.com or just open http://draft.blogger.com if you have already log in your blogger account.
2. select "Posting", then you should see "Edit Pages" as illustrated in the picture above.
Note: You are given up to 10 pages for your blogger account, so, please make them wisely to enrich your blog^^
