Hi all.

I'm having a problem in designing an e-clinic website for patients to make appointments with doctors. I built the login pages for the patients and doctors and am almost gonna do the dcotors' and patients' personal pages but I don't know how to do the appointments.
Is there any "all-purpose" appointments application with php and mysql that I can customise to my requirements somewhere?
Please help me out with this people.

Thanks in advance.
Sara
