A couple weeks ago, I implemented a wee bit of new functionality here on PewPewLaserBlog - a Contact form. Fill out the contact form to send me an email, even if you don't have a commenter account (or can't be bothered to remember it. You can even request a commenter account, if you like.
Since I implemented the feature 16 days ago, I've received one form-spam and one actual comment. I'm very pleased about the comment - it was kudos for a fix that I'd published on a discussion board.
