Be skeptical of anyone contacting you by only email, possibly claiming to be such-and-such SIGforum member, wanting either to sell what you're looking for or claiming to know somebody that has it and "here's their email address." That kind of thing is almost a guarantee they're scammers.
To protect themselves we recommended members require respondents post to the thread as well as follow-up via email.
