CalPress features

Hi,

I am thinking about buying the Pro version but I have these below questions,

1. what’s the difference between the different Pro versions?
2. can Pro set total attendance limit? for instance, allowing 1 attendee for one event and 3 for another, or set something like up to 10 attendees allowed to register?
3. does it support Chinese?
4. do members have their own calendar? if they pick up one event, would that picked event be shown in his personal calendar?
5. what about event organizer? does Pro support multiple organizers? would organizers have their own calendar?

I need this for an education project, so members in my case are students and organizers are teachers.

Thanks in advance!
