I found out that the current MSDN magazine has a list of tools available on the web. I have yet to see the copy so I don't know what all is on the list but I will be getting a copy at lunch.They list the Snippet Compiler and Regulator and others I will continue to list the ones I like. Regulator is a regular expressions testing and learning tool and wow is all I can say. I had used Expresso but Regulator is much better if for nothing else then its integrated searching for regular expressions. Have fun!
