*sigh* It looks like the comment spammers have found UNDULANT FEVER. In the last few days, I've had about a half dozen comment spams posted here. (Mostly linking back to weight loss sites, but one referring back to swimming pool chemicals. WTF?)
I've turned on the "word verification" setting to try and keep out the automated spams. This means anyone making a real comment will have to go thru an extra step. Sorry.
