Using Public Folders for organizational tasks

Have an IT request form (currently in the organizational forms folder) As is, people fill it out and it gets sent to several mailboxes.

I would like the form to be able to be filled out by anyone, but have the tasks go a public folder so that anyone in IT can see/complete/update said task.

I'd also like for any new task to send an e-mail alert to notify IT of the task...

Let me know how I can go about this. IF VB, please be very detailed in explanation. Much appreciated :)

Thanks
