Issue:
Regular Expression are quite power especially for validation purposes. Classic examples include password and email validation. However, regular expressions are usually something developers get to work then forget about. I don't work with regular expression everyday so I don't bother memorizing the syntax. So when I do need to use a regular expression in code I usually end up searching the web for an example.
Solution:
A coworker here at SpringPoint Technologies turned me on to Expresso, a free regular expressions authoring tool.
