Once upon a time, I used to write PHP scripts in my spare time which I offered for download here. I don't do this any more, since I don't have time to dedicate to it, but you can still grab the source of my most popular script, PHPAskIt, if you want it.
PHPAskIt was a question and answer (FAQ) script written in PHP and MySQL, which I originally wrote in 2005. It allowed visitors to ask questions which could then be answered by the site owner.
Please note: PHPAskIt is no longer offered here for download but you can find the latest version and the source on GitHub.
