Hosting a meeting in my 'personal room'

[Camra]

If I host a meeting in my personal room, is there a limit to the number of participants?

Can the meeting be 1 hour long?

Or is there another reason why I shouldn't use this for a parent talk?

The number of participants you can have in any of your meetings (Personal room included) is determined by your license type. https://support.zoom.us/hc/en-us/articles/201363173-Zoom-user-types-roles

Since you have a personal meeting room, you likely have a license. Understand Zoom time limits here: https://support.zoom.us/hc/en-us/articles/202460676-Understanding-time-limits-for-Zoom-Meetings

Its common for educators to use personal meeting links for both parent discussions or open office hours. Pls see here for meeting security best practices: https://explore.zoom.us/en/securing-your-meetings/
