Who cares. If they’re not here no troubles.
One evening, a very attractive young lady was sitting in a fine restaurant patiently awaiting her date. While waiting, she decided to make sure that she looked perfect for him. So the young lady bends down in her chair in order to get a mirror from her purse. Then just as the waiter walks up, she accidentally farts quite loudly. The lady immediately sat up straight, embarrassed and red faced, sure that everyone in the place had heard her. Quickly she turns to the waiter and demands, “Stop That!” The waiter looks at her dryly and says, “Sure lady. Which way was it headed?”
There are troubles. The more people on a list, the more work FR's server has to perform to get everyone notified. We went through a time a while ago, where longer lists were crashing the process, and we had to split them up.
Responsibly maintaining one's list(s) is a small part we can do to help FR function efficiently and successfully.
I routinely prune 3-4 names (sometimes more) from my list every quarter. I just check to see who has not posted in the last year, and they're gone.
