Several years ago I belonged to a forum (not horse) that allowed for one to start a private thread and invite others they wished to participate. For example, I want to ask something but know the particular subject causes a great deal of dissention and want to discuss with certain others with whom I was comfortable and whose opinions I respect . I could get several opinions without pm each one individually. It works well with controversial subjects. Would HF be in favor of developing something like this? Or can chat be made private by invitation (I admit, I have never tried chat, not sure how it works).
