Short articles are easier to fit in. Articles 300 words or more should have a subtitle every 150 words. Use newspaper style, with paragraphs of 1 to 4 sentences. Use concise thoughts to allow space for other contributions. Use military times, i.e. 1335.
Local time is understood.
Double space between paragraphs. See what it looks like. Editor will change the caps to underline, italics, or bolded as appropriate. Don't send all upper case material. Use calls only for club members.
