I have created a meeting workspace under an existing site, but there are less list types you can create for it. Since it is a 'meeting workspace' I am surprised that 'Calendar' is not under the list of types I can add. How can I add the option back (and any additional ones, e.g. 'custom list')?
I think that's not the way you are supposed to be using it. The way to go is:
This way, you have only one calendar with all the events, and each meeting has its own workspace. You also avoid schedule conflict
