Example: Recent Contributors box is visible on most pages at AboutUs showing portraits of last contributor.
The
Recent Contributors box shows
portraits of folks who have edited that particular page. It is essentially a visual and personal representation of the
wiki page's
history. You can click a contributor's portrait to go to their
personal page.
If a question mark is showing up instead of your portrait upload one this way. If a page has not yet been edited the Recent Contributors box invites the viewer to be the first to edit the page.
