Hi, I'm having a big issue about how to configure a Drupal site, I'm getting crazy.. My goal is something like this: A person works in 2-3 cities, he needs to be booked by his clients by an authomatic system. For example, he works: City A: Monday to Wednesday, 8am to 10pm City B: Friday, 9am to 11pm City C: Sunday to Wednesday , 7am to 12pm (every time it can change, not a regular schedule) every appointment can last for 1/2/3/4/5/.. hours (not just 1.30 or 1.42). So he has to be able to provide his availability (by city and time) Users have to be able to book/signup for a 1/2/3/4/5/.. hours, one user can't book at the same time of another one. I looked at some modules like Booking Time Slots <http://drupal.org/project/booking_timeslots> but it looks like not working, as well as Public Bookings <http://drupal.org/project/publicbookings> I tried signup module but still don't know how let it work as I need to.. do you have any idea? Thanks
