Submit to CoE #52 through blogCarnial.com. As mentioned earlier, this now requires you to log in. But once you have registered the submitting is actually easier than it was before, where you had to enter your name and email and add an annoying captcha. So I encourage you to not let this new requirement stop you, but go on and register.
Currently there are only 9 submissions, which will make for the poorest edition ever, unless you submit one (good) or two (better) of your own or any other blogger's post on evolution RIGHT NOW! Submit on the site, or leave the URLs in the comments here.
