If you have something to say about the topic of the post, please join the conversation.
But if you are chiming in to say “hello” to a friend, or ask them how their dog is doing (no name mentioned), please refrain from doing so. There are forums that are designed especially for personal conversation, many of which I am sure we are all familiar with, but this isn’t it.
And, does anyone else get tired of seeing the same person post and post and post and post, going on and on and on? In a recent letter, there were no less than 22 posts from the same person. Enough already. Make your point and move on.
