My dear beloved reader,

I know you’ve read more than one post similar to this one. It is unfortunate, but I do have to write you another “please don’t be mad I am insanely busy” post.

It is sad though — because these are the days one would like to journal meticulously, penning every single detail for friends and family to read, and for my own future entertainment. Instead, I will have to do with faint, faulty, fragmented memories from my defective mind; and make up the rest of it in my favor. I guess I’ll have to ask you to do the same.

Regards,
Arnab

I have a tiny hand in this mess, I'm the author of the quickly and dirtily written, ill maintained captcha module for Drupal. It sounds like a war cry in a HongKong action flick, but PWNtcha - captcha decoder, stands for "Pretend We
