Use standard punctuation, capitalization, punctuation, and spelling, so your posts are easy to read. Use paragraphs shorter than 24 lines, leave blank lines between paragraphs and after punctuation, and hit return after every 72 to 75 characters, so your posts are readable on any size monitor. The easier your posts are to read, the more people will read them. Please be nice to the other posters to the newsgroup. Similarly, please don't flame others.
Constructive criticism gets better results than insults.
Please send private responses over email. If you aren't sure if it should be said, take it to private e-mail. Better yet, don't post a followup or email a reply at all. If there is no other forum for the discussion posters tend to be slightly more tolerant of off-topicness. Even if you want to buy an X-Men comic, or want to know how much a book is worth, ask over at .marketplace.
