Online Calendar HELP
Iím trying to find a calendar online that allows or is the following.
B.Allows users to enter in a time slot when they want a meeting. E.g Tom and Jo want to meet with all the employees in HR. They only have 45mins for each person. I need a calendar that would allow each person to chose 1 slot and only one person can use that slot. So Henry wants 9 and so does Susan. Henry manages to book it so Susan takes the next available time which would be 10.
C.Is not google calendar of Officezilla as these are not compatible with internet explorer or they are banned by the servers.
D.Is compatible with Internet explorer 6
Any help would be appreciated. Thank you
