How many forum members does it takes to change a light bulb?

One to post a thread about changing “light bulbs”, another one to express his feeling of Déjà vu and a third one to point out that it’s actually “lightbulb”. Then we have number four who complains about the original post, and a fifth one sharing his experience with a mercury filled lightbulb.

And finally the sixth person who has to point out that it has been posted before, and while he’s at it, complain about using the search function of the forums.

Six unicyclists and still no lightbulbs changed.
