Template:Todo
From 2009.igem.org
You can use this to mark something as TODO. It has one optional parameter and can be used as follows (assuming a style sheet is used to color all items with class todo red):
{{todo}} Something I've been meaning to finish. ... {{todo|Something I've been meaning to finish.}}
With the result:
TODO Something I've been meaning to finish. ... Something I've been meaning to finish.
