This list is information - you can take it or leave it. State your case, and let it go. Being a top-dog on the monthly posting ranks isn't really a goal to seek, unless your posting has content. Quoting an entire digest is a real no-no, I usually send private email to the perpetrator after it's done the second time. Learn to type.
Paragraphs are easy to do - and extra hit of the enter key.
Capitals aren't necessary, but often enhance readability. Context and attribution Quite a few messages on the mailing list, as in news groups, are replies to previous messages that hopefully carry a discussion along. When you reply to another's message, it is helpful to other readers if you put your message in some sort of context. This is particularly true if you are responding to someone else's comments. Usually it is easy enough to copy the original's meaning to your own posting.
