We have a situation where our client has multiple calendars in Sharepoint. For instance, Sales Calendar, Production Calendar...etc. When you login to Sharepoint on the home page, there is a Public Calendar. They would like if say a sales users adds something to the Sales Calendar, it also updates the Public Calendar...same with a production user adding something to the Production Calendar. That way when anyone logs in to Sharepoint and sees the Public Calendar, company wide can see whats going on with Sales, Production...etc. Anyone have any ideas?
