Want a way to say "actually I didn't testsolve this puzzle"

[purpleshiny]

I'd like a way for people to put their status on a puzzle back to "hasn't looked at it". Perhaps an option in puzzle feedback, or just a link on the puzzle's testsolving page? I want it to be easier to browse through the puzzles that are available, without making it so that you can't testsolve if the puzzle gets revised (assuming you only glanced at it). Yi-Hsin and Lanthe say it's a reasonable feature to have.

Learning how to wrangle PHP is fairly low on my list of life priorities, so I'm not super likely to implement this pony myself...
