It looks to me like the tread type that routinely gets shut down here is requests and offers to learn Vietnamese. It also seems that people are resisting using the classifieds for this as they repeatedly post in the open forum. I believe that many do not see this as a commercial transaction as much as a personal interaction. Could I suggest that site management should instead create a special sticky thread for this topic. Prohibitions against posting personal details could still hold but perhaps these questions could be allowed only in this thread. Both those seeking to learn and those offering to teach should be allowed to post but they must make contact via PM. Then if these things pop up in the forum, shut them down at once with a full deletion.
