Enbarking on a Project

Yay! just got an assignment by pastor Cuixian! I have been tasked to create a room booking system, and I'm up to the challenge! one problem now will be to find out how to send mails using my web server. I have already devised a way to handle the room booking requests and approval, coding it would be challenging, but apart from the emailing part, I believe I have all the tools required to solve this problem using PHP and MySQL... Hopefully this system would eventually be implementable... If it happens, it'll be the first useful program I've written.
