Previously there is a mention for a reconfirmation, I thought about this for a while and realise its a bad idea, because, supposing you book a Meeting for the 1rst day back after a Holiday, then the auto cancel will remove the Room.
In our Organization we prefer to send a Reminder Email with a link to the booking, giving them the option to release the room if they do not want the room.
The script can be triggered on Access, for example in the index.php, a kind of user driven cron, and a separate Cron ran once a day, cron entry is something like php myscript.oho.
Any way I dont mind writing this script, but can I have a little guidance on which calls I should make, so I can speed up the writing, maybe a possible function that is close that I can mod. Once done, ill post it back here.
