Hi I find it surprising that such abuse would come from a group of people with the credentials found here. You should ALL know better. You get free, good service and bitch when there's a problem and it's not resolved in as timely a fashion as you would like. Sheeeesh.....! Were it I, I'd've unsubbed you. Kudos on a job well done.
