How do I edit my attendee list for a meeting next month?

Hi @pacaman 

If you need to add or delete attendees, you can do so from your calendar (To: or Add Guests on calendars). 

There is no need to update the meeting on the Zoom scheduler. 

You may also click on this article for further information. 
Should you need further assistance, please let us know.

As I umderstand it, I do not have access to a calendar (I am a single month subscriber) and when I spent some time on the 'phone trying to get some help I was informed that my particular purchase didn't include person-to-person contact!
I  am still at a loss as to how to amend my contact list - but thank you for the repsonse, I appreciate it.
