Please excuse me, but I just recently had to turn down a client when I realized exactly what he was wanting to do -- generate spam to promote a pyramid scheme MLM. I guess I was just a bit on edge about spam at the time. Regex in C is really not that hard, but you do not get the fully extended stuff perl offers. The reason a spammer would want to use C is the same as yours: speed. Imagine harvesting millions of email addresses every day from newsgroups, mailing list archives on the web, and just about anywhere he can find them. That is a lot of text parsing! -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
