When you have finished writing and editing the article or reply, and EXIT from the editor, you will be given a chance to send the reply or article . The default editor for Tin is PICO, unless you have changed the default editor for your account or within Tin. At the newsgroup selection level, select the newsgroup you want to post to. With your cursor below the section for Keywords, type in your article.
Many people have the habit of skipping any article whose first page is largely quoted material.
Format your article to fit in 90 columns, since that's the conventional size. If your lines are too long they'll wrap around ugly and people won't read what you write. If you aren't careful and considerate in formatting your posting, people are likely to ignore it completely. It's a crowded net out there. Enter p to post the article.
