Just one word of caution. I've seen several Zoom meetings on YouTube recently and whilst the conduct of members of the council during the meeting may be acceptable, some of the casual chit chat whilst waiting for the meeting to commence is cringeworthy! This can be edited out, but many people seem unaware of this. Similarly, it goes without saying that if the council goes into closed session during the meeting, this section must be edited out.
