Daily Entry Limit

Hi a couple of questions before we buy your program -

1. is there a limit on how many events i can enter in a day?
2. can i have multiple events all on same day starting at same time in different categories?
3. can i have multiple events all starting at the same time in the same category?
- this is for regional events that occur on the same day and start at the same time -
for example; Race 1 starts at 10am in Los Angeles - Race 1 Starts at 10am in San Francisco on same day -

look forward to hearing from you
thanks
