Since I'm a programmer, I usually find myself needing to write regular expressions from time to time.  Now, I'm no expert but I think I can hold my own... with the help of my trusty ReGex cheat sheet.  The problem has always been that I'd have to implement the ReGex() code, then write the expression and test to be sure it worked.  Not ideal.  So today, while finding myself, once again, needing to write a regular expression I stumbled across this very nice and simple online RegEx validator.

I know what you're thinking, "I could write that in 10 lines of code or less" -but alas, you didn't!  So until you, or I for that matter, write one of our own and put it out there for the world to see, this is a nice alternative.
