[FX.php List] Multiple Page Forms: Unsetting submit button

[DC]

since ereg() is case sensitive you will need to modify your regular  
expression to include capital letters.

i like preg_match() better than ereg() since it is said to be faster  
and is more flexible with the ability to do case insensitive  
switches, etc...

also, the reg exp itself could be better for email detection. see  
this site/page for a great example and tutorials:

http://www.regular-expressions.info/email.html

good to see progress!
