Wikipedia:Tip of the day
Template messages vary in their placement. For example, a {{merge}} notice goes at the top of the article, but the {{stub}} message goes at the bottom. Read the documentation at the bottom of a template for instructions on how to make use of it.
The Tip of the Day was started on as an original feature of the newly created Community Portal. There were about 50 tips, displayed over and over.
In 2006 the project was revamped and expanded to a tip page for each day of the year. Later that year, a "yearless year" was created, with no year included in the page titles, so that the same pages could be displayed automatically year after year. The tip collection grew to about 300 tips.
