Posting etiquette

I would like to suggest that you send reminders to people from  time to time concerning etiquette. Every now and then people veer off and get a little testy, it seems, and some also post irrelevant or "off-topic"  comments which by themselves would warrant starting a new thread. I also would urge some people to write using shorter paragraphs!! Or at least divide their paragraphs into two or three parts. 

Thank you,
