Just to clarify, DFing announcements are not always made during the "announcement" part of the meeting. If an Elder who was on a committee has a part on the meeting, he may make the announcement at that time, or if it's an announcement that may be upsetting, I've seen it wait until the end of the meeting. No rules on that.
I do have to say, that you got guts, making the announcement yourself. You made your own terms.
