There is nothing in the legislation or elsewhere that prevents you from including an agenda item of general business or any other business or anything else you want to call it. You can include items where particular information is noted but no resolution is attached. You can have an agenda item for discussion of the situation in Libya if you want to. Major listed companies have items for discussion and noting on their agendas as a matter of course.
It is up to the OC to decide what it wants on the agenda – as long as it includes what is required by the legislation that’s fine. It is true that often this is the only time some owners front up or communicate and the meeting is a good opportunity to raise any issues or concerns they may have.
An additional safeguard if there is any concern about confusion as to whether it is a resolution or merely for discussion/noting is to include a note in any agenda item like that making it clear that it is not a resolution. At the top put FOR NOTING/DISCUSSION.
