List of C# API that don't do anything?

[abc123456]

I poked around the C# API. I could not get some of the functions to work so just wondering if they actually work? Here is the list of functions that don't seem to do anything:

OnDoMeetingInMapEvent

    CampaignEvents.OnDoMeetingInMapEvent.AddNonSerializedListener(this, new Action<MobileParty, List<CharacterObject>, int>(
            (party, list, num) =>
            {
                InformationManager.DisplayMessage(new InformationMessage("asdasd asdasd"));
            }));
