As soon as you figure it out, I’d like to know as well! I like the service that the Knowledge Exchange provides, but I get too many emails, and the options to change it (like to receive one “digest” email a day) do not work. I’ve tried changing the setting to “send me NO email” and I still get them. My next step is to completely block any emails from this domain, however I don’t like to take such a severe step because I do receive useful information from time to time. Hey guys at ITKnowledge Exchange, I think you need to address issues with your service lest you begin losing people left and right!
