I've been thinking of writing this since april 1st, but haven't got around to it. But it's been fun seeing the occasional person falling for the prank afterwards even though there is a sticky post in it which explains it. =]
Can't think of many others who will have any use for this though, but I thought I might as well release while I'm at it. I was going to ask if anyone was interested first but it's such a small hack that writing the instructions took about the same amount of time. =]
