I guess I may as well post another "gripe", to get them all out of my system. This relates to the courteous way to send a reply to an email.
The only sensible reason to send back previous messages is to leave just enough to assist the reader to understand one's response. Unfortunately, too many folk just hit the Reply button, and type away.
If there's just one message, it's not much of a problem, but I belong to several church-related groups, and often a topic is commented on by many different people--and, on many occasions, the thread will contain more than one message from the same source.
Last week, I received a message on a very long thread. There were five previous messages in the same thread, and they weren't all brief. I had to spend what seemed like two minutes scrolling, scrolling, to get to the first message so that I could delete the long string of peoples' opinions.
Hence my request to those who post: edit you response, please!
