Hiya, welcome to Sarna!
It is normally frowned upon to edit another person's userpage, but I've taken the liberty to help you out a little with the formatting. Keep in mind that wikicode isn't WYSIWYG. Adding a space at the beginning of a text line, like you did for indenting your paragraph beginnings, creates those weird boxes that don't even scale to the actual text. And a single carriage return will be ignored when displaying text, you need to use two CRs (or insert <br /> to force a line break).
