Here's a start:
View | Reports | Customize
In the popup select "Resource" and click on the Edit button
In the popup select the "Details" tab and clear all checkboxes except for Calendar.
If this report is 'generally' what you want but you want to get rid of the extraneous columns like "Material Label", "Initials", etc., then
View | Table:xxxxxx | More tables...
In the popup click on "Entry", click on the "copy" button. Change the name of the table to something like "Entry - Calendar" and delete the rows of data that you don't want. Click on OK then click on Cancel.
View | Reports | Customize
In the popup select "Resource" and click on the Edit button
In the popup select the "Definition" tab and set the Table field to whatever table you defined a moment ago.
And in anticipation of your next question: no, there is no way to print out month-by-month calendars (using the canned report) for each resource.
And in anticipation of your next next question: no, there is no easy way to export this to Excel.
And in anticipation of your next next next question: yes, it could be done in VBA but it will be involved and I don't have a code fragment that can start you on your way.
