Hi Loyd,

Thanks for your continued contributions to the Teachers' Lounge, and
for flagging this recent wave of abuse.

In our daily monitoring and sweeping of the spam these past several
weeks, we've also gone on to analyze our access_log to identify the
responsible IP addresses. 

Despite denying dozens of malicious machines from accessing our
website, others have continued the onslaught; in fact, they have
similarly attacked a wide range of Math Forum web page posting forms. 

So we've recently vetted several ideas to redress this ongoing
annoyance, including the deployment of a "captcha" challenge-response
system -- the kind commonly found on other sites.

Thank you for your patience and vigilance, Loyd, as we resolve this
problem.
