Template:Projectinprogress
From Appropedia
To implement this template, place the following code at the top of your project page:
{{Projectinprogress|Month Day, Year}}
The template categorizes the including page as [[Category:Project pages in progress]].
Some time after the date has expired (perhaps allow a margin of a month or more, in case work is still going on?) other editors may remove the tag and edit the page as appropriate.
