I have many people accessing my calendars, and I want all their added entries to show, but I only want them to be able to double click and open the entries which they themselves made. Now they cannot edit someone else's entry, but they can open it and read that private information. Any thoughts???
You could create another calendar and then write a workflow which copies events from your entry calendar to the other one but without details or whatever fields.
YOu'll need to handle updates which I believe you should be able to do.
Just add a field on the second calendar called 'ID-org' - set it to the ID of the entry calendar entry and then you can look up the corresponding event on the second calendar.
There's an issue with handling deletes -you can add a delete option to the entry calendar - field called 'Delete?" which is yes/no. Then the workflow could delete the second calendar entry. Hide the delete buttons from edit and disp forms (easy - just look at the CSS for those buttons via Firefox inspect element (Q)'
