I got an email notification about a new user in my webpage. I am the only user and the author. The email:

New user registration on your site LIVING WITH ALLERGY:

Username: BLANCA22Burch

E-mail: [email protected]

How could it happen? I removed the new user immediately, I changed the password. What else can I do to avoid this problem in the future?

Themes:
I am trying the Suffusion Version 4.4.6. But I have tried Twenty twelve, twenty Ten, iPage, no one let me see the pictures on the posts.
Links:
The “Related articles” linkes are not active either.
Previous contacts:
I can not find my previous followers, my Gravatar.
Stats:
The stats showed zero when I started at HostGator, and just started to work a few days ago, when I downloaded a new stats plugin. (Should the old stats work? Or when a host is changed, it doesn’t work anymore?)
Archives:
The Archives in the menu bar empty. On the side bar the Archives show the previous blogs. This is ok?
Pictures:
The pictures are also ok on the OLD posts.
I have downloaded the Zemanta plugin, it is working good on the edit mode, but not on the published post. I used to use Zemanta, I would like to use it again. It is very useful for pics and links.(if it is working)
I am a beginner, started just a few month ago and these things are very confusing for me. I would like to try a free version first to learn more about how does it work.

Thank you for your help.
