[clue-admin] contact form spam

[Jeff Cann]

It seems like someone is trying to spoof the contact form (see below - 
embedded message).  I'm not sure if the spammer is trying to submit the form 
or what.  Should we hook up a captcha?  It's not foolproof, but on my blog 
(isuma.org) it took care of comment spam.

Any other ideas on how to stop this nonsense?
Jeff
