Excellent! By using both of your codes, the Captcha and the Question, the SPAM problems have been resolved.
For others interested in the Captcha solution, the previous website which hosted and developed the Captcha software is no longer available. However, I've attached the zip file of the original Captcha software to this message in hopes of helping others. In summary, use the zip file to get the Captcha code and images, then use PerlFlunkie's code by following his helpful step-by-step instructions.
PerlFlunkie, thank you for all that you do, it makes a difference.
Keep up the great work and spirits!
