1. When scheduling for an event, is there a way to get notified of a time conflict. So far, I am able to schedule events at the same time, without the system telling me something is already scheduled. 

On a further note, anyway that a)  the date can be surpressed in a report or dashboard view and only the time shows and b) anyway to change the time selection to a 24 hr clock, instead of the am/pm selector

2. In my company with have a number of rooms for training purposes. Is there any resource management function in Zoho. I can't find it. Basically I need to be able to see if there is a time slot available for a session within these rooms.

Any help would be greatly appreciated.
