Userboxes are used to decorate user pages and to tell little details about yourself. They've become a fun tradition on Wikipedia. They are easy to design, and require just 3 things to make them: the userbox template, the name of an icon image page, and a blurb that you type in. To see the code for the userbox included here click "edit this tip." There are also hundreds of premade userboxes to choose from that other users have designed.
Userboxes help other Wikipedians to know a brief summary about you, you can tell other Wikipedians that you come from Switzerland, like classical music etc. To avoid creating a mess with the userboxes (meaning that they mix with the text and cause mass havoc on your userpage) try and create a table so that they will appear along side the text without formatting problems.
