How to review user contributions

To see a list of a user's contributions, go to their user page or user talk page. When you do that, the menu item "User contributions" will appear in the Toolbox menu on the sidebar. This link will show you all the edits that user has ever made (except deleted edits), up to 500 per page. This is useful for tracking vandalism in progress.

Edits with a "top" link are the most recent ones to their respective articles.

You have your own contributions list, which is particularly useful for tracking your conversations on talk pages. If you are logged in, you can access the list from the "Contributions" link at the top of the page.

To help keep track of your discussions on talk pages, you may wish to place the {{Discussion tracker}} template to your talk page.

To add this auto-updating template to your user page, use

Two species of sea urchin
Sea urchins are a group of spiny globular echinoderms which form the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal to 5,000 metres (16,000 feet; 2,700 fathoms). Their tests (hard shells) are round and spiny, typically from 3 to 10 centimetres (1 to 4 inches) across. Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessile animals. Their predators include sea otters, starfish, wolf eels, and triggerfish. This photograph, taken off the northern coast of Haiti near Cap-Haïtien, shows two species of sea urchin: a West Indian sea egg (top) and a reef urchin (bottom).Photograph credit: Nick Hobgood, edited by Lycaon
