In tools-options- there is a spot on the bottom which says _CALENDAR OPTIONS_
Change the drop down to BREW LOG ONLY and click the checkbox- HIDE RECIPES WHERE IM NOT THE BREWER
Now when you make a recipe it wont show on the calendar until you select the recipe and hit the COPY TO BREWLOG button. This keeps any recipe ideas you have made off your calendar and will only put recipes in the brewlog where you are listed as the brewer on it. Goodluck!
