|UPDATE: I have implemented some new anti-spam tools and rehabilitated commenting.
I'd appreciate it if you were to contact me at the first sign of trouble, like with Captcha (the 2 words you now have to type at the bottom of the comment form), for example.
You may also be pleased to know that your efforts digitizing the "dancing letters" will not go to waste, because this specific implementation - named reCAPTCHA - uses your input to help digitize words in scanned books and other printed media that OCR can not decipher. For more information, click here.
22/03/2010: Unfortunately, comment spam has risen to unacceptable levels lately, forcing me to turn off the commenting option in this blog.
If you'd still like to comment here as a visitor (members may always comment), please send me a message through the email form, and I'd be happy to post it for you.
