Fans of regular expressions often pull off some tricky search/replace transformation by writing up an incomprehensible regular expression.
Then next time a similar transformation is needed, it takes almost as long to write it up again. No good!
If you find yourself writing regular expressions or scripts to do a text transformation you know you've done before, submit it to the Supernifty Text Transformation Library, so others can use it, and you won't have to remember how to do it next time.
You can also see if someone has already built a transformation that you can use, thus enabling essential brain rest time.
