Actually, this is a "discussion" type of forum ... we do not have the capability of "live chat." Chatting, at least to me, is when a group of people are engaged in constant conversation, which is not the case here. We do not have "chat rooms" associated with this forum community.
Yes, we do "chat" amongst ourselves in the open discussion areas like the Community Forum area, but as anyone can see, we do have structured topical forums where the idle "chit chat" is kept to a minimum and the ensuing discussion is about a topic of several topics.
I do hope your family will take a look around at the plethora of topical discussions ... some discussions have no input for several hours, days or even weeks ... hardly could be construed as chatting, imho anyway.
