When you care enough to tell a current lover or former trick that you might have given them a sexually transmitted disease—but are too chicken to do it face-to-face—look no further than inSPOT.org's new online card notification service: messages are available in colorful text or tasteful beefcake designs, and all may be sent anonymously if you choose. (Personally, we prefer sending flowers along with a handwritten note, but we're old fashioned that way.)
