Hello Tuan,
in my eventbooking for Joomla 3.0 it is impossible to check all events by klicking the box beside the NUM on top of the columns - this is a pain if you have to (un)publish or delete more than one or two events
And with recurring events I cannot see any more if it is the parent or child event as I can with Jooma 2.5
Just wanted to inform you
Claudia
