I've noticed on certain websites, be it MSN or YAHOO that you sometimes get
asked to enter a set of numbers and letters before an email can be sent.

I'd like to know what this technology is called and whether there are any
articles discussing how to implement this (or even code)

Thanks in anticipation for your help. !!!

Thank You for all my responses. Would anyone know if there is any native code
that would work within Frontpage for CATCHA ?
