What's up Greg? Hope you are doing well.I use Akismet (I misspelled this
oringially   but I corrected it and linked it). Perhaps by definition it is not
CAPTCHA.Regardless, it is a WordPress plugin that identifies and blocks comment and trackback spam.
It works great and means your readers don't have to:1) Wait for their comment
to be moderated.2) Type characters into a box.So yeah, it's great. Good to see
you are reading the blog. I really appreciate it, and I'm flattered.
