One of the most important rules in software development is not to trust
user input..... ever!


_javascript_ is an excellent scripting language providing a user friendly
1st layer of notifying problems, fast, and responding to those problems
with another piece of _javascript_. Whether is it displaying an alert, or
showing a red border around the formfield containing the errors.


But.... you should always check user input again, on the server side. I
am able to change everything within _javascript_, I can fake every
formfield if I want to. If I can do it, certainly somebody else also.
