Hi Kriss,
After reading all these posts, I am bit confused as well. You mentioned,
My goal is to keep the registered client updated and be able to receive appointment scheduled for delivery.
I would think this means you want some sort of notification application that allows you to set the date and when the user logs in they see the date you posted.
Who will be entering the date? The client or you or both?
Will this date be changing from time to time? or is it a permanent part of the client's profile?
It looks like you and Nick might have been talking about two different things. Sorry to go back to the beginning on this, but I think a clear picture of what you want to do will get us back on track.
Cheers,
Ed
