There are times when a long thread is going and we are no longer a part of but continue to get emails about postings. It would be nice if we could unsubscribe ourselves from the thread. If it was just for 'Ask the Expert' that would be a huge improvement.
If I'm understanding your question there is a solution to your problem. If you want to unsubscribe to any thread on NetPro all you have to do is click on the 'subscriptions' tab and uncheck the box of the conversation you no longer want to receive emails for. Does that solve your problem?
