Ahh, the ZohoPlanner have the coolest implementation of Ajax! Great and good work.

The navigation is so systematic. Yet, I have no idea where I should click "Help".

Anyway, some questions rise from my mind. First, if it's free service, so how can the company survive? Second, How many MB is the storage to keep all of the pages? Is it unlimited?

For the programmers, thanks 4 ur hardwork in this service.
