As I am a member of several Mayo Clinic groups, considerable email from Mayo arrives in my Inbox every day. Sometimes I feel I just can’t take the time to have a look even though there may be something there of particular importance for myself or that I would want to comment on. My question is about for how long will the comments I may have a particular interest in, remain available? Can I always go to a particular item and find the comments made on it, maybe months ago? Are comments removed after a certain amount of time? I have been unsure where to post my concern and just arbitrarily picked this location. I hope I have made my question clear!
