Userboxes are templates that are designed to be added to a user's userpage. To add userboxes to your user page, first you need the area to contain the userboxes in. This can be done by typing {{userboxes}} and {{userboxesend}}. Doing so will produce this:
Userboxes
Next, select userboxes from the following list and add them to the page. They must be placed between {{userboxes}} and {{userboxesend}}. All userboxes use the base userbox template, which you can see for information on creating userboxes.
To add a userbox to your user page, simply find it in the links below and then copy the code onto your user page. For example, placing {{Pastime EditsWiki}} on your user page will add this to it:
This user edits the wiki when bored.
Whoever visits your user page will see that infobox on it.
