The final option menu I will go over is the alarms menu. This is part of the clock's properties. This allows you to attach a sound or text pop up to events and times. Some of the events that you can choose from are Corkboard activated, Corkboard deactivated, new object, object deleted, etc. These are just three of the menus for three different objects.
Most objects have some sort of property menu, and all are pretty self explanatory.
You should be careful though, and read over the menus. They are very thorough and there are a lot of cool little options that you didn't notice before. After about an hour you may discover that the selection of objects is severely limited. In fact, the program would only be marginally useful, and not very fun at all if it weren't for the expansions. You can download these which are from one to two megabytes each from the Corkboard website.
