There are some very good posting guidelines here.
I have a suggestion for one more, it's just a thought, and may just concern me. When I was sick, strong colours made me ill. New commers sometimes write with bright, strong colours. Strong colours actually "hurt" when I was sick. My mum sees this in a lot of her very ill patients. At her work, strong colours are banned from very sick patients rooms unless the patient is able for them. I know flashing and moving avatars are asked not to be used. Pherhaps one can ask people to write in plain old black, or "soft colours"?Tthat is, if I am not the only one who has experienced this "problem".
Just a thought........
