The Expression Toolbox was created to help take the pain out of using and locating expressions. At some point you've probably come across an expression that you find yourself using on every other project you work on. The question is where do you store this expression? I noticed that a lot of people were storing their expressions in text files, without documentation of how they were used or where it could be found. Without knowing who created the expression or how to use it, you're left waiting on an answer from a mailing list or web forum on how to properly apply it.
