Because we didn't have a test module when we first set up the event, we tested it/practiced by entering fake information. It ended up wasting hours of my time, because I couldn't simply go back and delete the practice entries. I had to hunt down every tab that might have saved info from the original entry and delete each one individually. Crazy! I should have been able to select the entries for deletion as a batch, and that should have included all of the affected tabs. A warning dialog would be an important safety feature, of course.
